| Abstract: | The abrasion wear resistance of stainless steel and composite stainless steel/titanium boride coatings arc sprayed with air
and argon was evaluated. Stainless steel coatings arc sprayed with air were found to be slightly more resistant than bulk
stainless steel, whereas those sprayed with argon were slightly less resistant. The wear resistance of composite stainless
steel/titanium diboride coatings was from two to four times greater than that of bulk stainless steel, depending on the cored
wire constitution and the type of gas used for spraying. Microstructural analysis, microhardness measurements, and optical
profilometry were used to characterize the coatings and wear damage. By considering both the wire constitution and the spraying
conditions, it was possible to fabricate composite stainless steel coatings that showed a 400 % increase in wear resistance
over bulk stainless steel. |
