| Abstract | |
Failures in structural components due to cyclic loading are associated with materials surface damage. Coatings deposited by different surface processes are more or less effective to improve the degradation resistance of diverse elements. The present study aim is to analyze plasma immersion ion implantation (PHI) effect on axial fatigue strength, corrosion and wear resistance of AISI 4340 steel. Experimental results indicate an axial fatigue strength increase for 1, 2 and 3 h of treatment. PIII treatment was not effective to protect AISI 4340 steel against environmental aggressive action. In abrasive wear tests, lower pin mass reduction was observed due to superficial treatment. (AU) | |
