Although stabilized alloys do not require high-temperature annealing to avoid intergranular corrosion, the stress-relieving temperature exerts an influence on the general corrosion resistance of these alloys.
Despite the growth of alloy steels and special means of surface hardening, the ancient art of carburizing steel remains one of the fundamental operations in the manufacture of machine parts.
Congratulations to Mr. Douglas G. Puerta, Director, Aerospace Product Qualification Testing, Element Materials Technology, who has been elected to succeed me as President of TSS.
The basic components and design of a dc plasma arc gun are illustrated in the diagram. Direct-current plasma arc guns combine an axially aligned cathode, an anode/nozzle, and some means to control gas flow geometry in the arc chamber.
Ipsen, Cherry Valley, Ill., recently installed both atmosphere and vacuum heat-treating systems at SKF’s state-of-the-art manufacturing facility in St. Louis.
