Tribological and high-temperature mechanical characterization of cold sprayed and PTA-deposited Stellite coatings
Stellite 6 is a cobalt-base alloy commonly used for coatings useful in wear and corrosion protection of several components over a wide range of temperatures. Stellite coatings can be obtained by many deposition techniques: plasma transferred arc (PTA) is certainly an optimal choice that gives thick, dense coatings, but thermal spray techniques like high velocity oxy-fuel (HVOF) are also widely used to deposit such materials.
