Ipsen answers maintenance questions for vacuum heat treating systems
February 10, 2016
Source:
Ipsen, Cherry Valley, Ill., reports that its "Finding Leaks in Your Vacuum Furnace" blog series takes a close look at how to determine whether the furnace or the pumping system is the root cause of vacuum-related issues. For example, some people might immediately assume something is wrong with the furnace when it begins to present signs of outgassing, dirty parts, performance issues, etc.
While it's possible that the furnace could be the source of the problem, it is important to avoid wasting valuable time going through all the steps of leak checking the furnace only to realize that actually something is wrong with the pumping system. Therefore, Ipsen experts outlined a few simple steps for determining whether the furnace or the pumping system is the guilty party in their newest "Finding Leaks in Your Vacuum Furnace" blog post; find out what these steps are at http://bit.ly/LeakCheck-10.
Ipsen's blog, "The Ipsen," Harold, also features informative videos, expert tips, throwback photos, and useful resources, such as A Daily Checklist for Preventive Maintenance and their ongoing series, A Look Inside the Furnace (which examines hot zone types, best practices and maintenance).
Focused on sharing tips of the trade, as well as breaking down technical and complex material, this blog provides readers with valuable, up-to-date thermal processing information. Be sure to check out Ipsen's other posts and how-to videos on their blog, The Ipsen, Harold.

Message from the President: Sad News from Minneapolis
Source:
On January 28th, Prof. Emil Pfender from the University of Minnesota passed away at the age of 90. Prof. Pfender carried out pioneering work in the science and technology of thermal plasmas. In particular, he made exceptional contributions to our fundamental understanding of plasma arc dynamics, as well as the heat and momentum transfers to particles in thermal plasmas.
Prof. Pfender was co-founder and co-Editor-in-Chief of the journal Plasma Chemistry and Plasma Processing for 25 years. He also co-authored, with Profs. Pierre Fauchais and Maher Boulos, the highly cited book, Thermal Plasmas: Fundamentals and Applications. Prof. Pfender was elected to the National Academy of Engineering in 1986, and received numerous prestigious awards for his internationally recognized work.
Beside his exceptional career, Prof. Pfender was an extraordinary human being. When I met him for the first time in the early nineties, I was immediately impressed by his calmness, imposing presence, and serenity. He spoke slowly with a charming smile, not only about thermal plasmas, but also about his passions for old airplanes, trees, and for his children and grandchildren. He was always respectful of others' ideas, and expressed his own opinion with clarity and simplicity. In fact, he was a real gentleman!
We will miss you and your comforting presence, Emil.

Spray Tips: Plasmas
February 8, 2016
Source:
The plasmas under consideration here are part of a class called thermal plasmas or plasma arcs. The graph shows the transitions in state as plasma current increases. Thermal plasmas begin at approximately 10 A.
Plasma, often called the fourth state of matter, normally consists of neutral atoms, positive ions, and free electrons. Plasma is produced by transferring energy into a gas until the energy level is sufficient to ionize the gas, allowing the electrons and ions to act independently of one another. The plasma state is achieved when, under an electric field, currents can be sustained as the free electrons move through the ionized gas. After the energy input is removed, the electrons and ions recombine, releasing energy in the form of heat and light.
It has been estimated that 98% of the visible universe exists in the form of plasma. Plasmas occur naturally on Earth as the aurora borealis, aurora Australis, St. Elmo's fire, and lightning. Common man-made plasmas include neon and fluorescent tubes and bulbs.

Accuride steel wheel coating technology enables six times longer life
Source:
Accuride Corp., Evansville, Ind., announces the launch of its proprietary EverSteel wheel technology, which has demonstrated six times longer life than its North American and offshore competitors, and double the operational life of Accuride's Steel Armor steel wheels.
First, EverSteel metal surface treatment is applied to the bare steel to protect it from harsh daily wear and tear. This is followed by a zinc phosphate pre-treatment that prepares the metal for maximum adhesion. Then an enhanced cathodic epoxy electro-coat optimized for sharp-edge and overall corrosion protection is applied. Lastly, Accuride's Steel Armor premium powder top coat is applied.
By bonding EverSteel technology with its Steel Armor powder coating and a high-performance epoxy electro-coat, Accuride has developed an enhanced protection system that delivers unmatched corrosion-resistance and longer wheel life. EverSteel forms a tough barrier that isolates the wheel from the harshest of elements and makes it resistant to chips from normal road wear.
The advanced corrosion-fighting properties resulting from EverSteel's proprietary four-phase coating process deliver unmatched durability and wheel service life. This enables Accuride to offer customers the industry's first warranty against steel-wheel corrosion with EverSteel.

TWI and Metalysis demonstrate selective laser melting for 3D printed tantalum implants
Source:
Metalysis, England, has collaborated with TWI, also of England, to demonstrate the feasibility of its tantalum powder in metal additive layer manufacturing for biomedical applications such as patient-specific hip joints. Metal 3D-printed hip replacements could be a huge step forward, allowing patients to have a tailor-made joint by scanning their other hip and matching it with a metal 3D-printed replacement, rather than being restricted to the choice of standard sizes now available.
Metalysis' high-quality metal powder, combined with TWI's expertise, has demonstrated the significant potential of creating lattice structures via selective laser melting (SLM). The technology si suitable for hip joints, implants, and other new biomedical products that will benefit the patient and bring cost savings to the wider market.
The study successfully produced both uniform and randomized tantalum lattice structures that are bio-inert, replicate the structural stiffness of bone, and allow for extensive integration with bone cells, so that the new joint may be readily accepted by the body.
Metalysis has developed a process that produces metal powders directly from their respective oxides in just a single step, significantly lowering the environmental impact of its manufacture. The innovative process is not only cost-competitive, but also produces perfectly spherical metal powders of uniform size. As a result, the end products of metal additive manufacturing are structurally consistent with an improved as-built surface finish.
This study has shown that the durability and inertness of this highly versatile metal are retained through the production process. This is due to the quality of the powders, which allows the 3D printer to lay down the metal, forming a lattice structure with consistent strength and density.
Research specialist TWI has a history of bringing advances to the medical industry, and this study shows that Metalysis' metals can be used to manufacture prototypes of the highest levels of quality by exploiting SLM additive manufacturing technology.
Metalysis is spearheading a revolution in the production of high-quality metals, including tantalum and titanium. Its patented process replaces the outdated, extremely expensive and highly toxic Kroll or Hunter process, which has been used for the past 70 years. Up until now, the inefficiency and expense of this process has made titanium and tantalum prohibitively expensive. Since the launch of its commercial plant in 2015, Metalysis has been supplying tantalum powder to its clients globally, working in collaboration with LPW Technology to serve its additive manufacturing customers.
