摘要: Abstract Wear resistant Cu-based solid solution (Cu ss ) toughened Cr 5 Si 3 metal silicide composite coatings were fabricated on austenitic stainless steel AISI321 by laser cladding process. Due to the rapidly solidified microstructural characteristics and excellent toughening effect of Cu , /Cr have outstanding wear resistance low coefficient friction under room temperature dry sliding test conditions coupling with hardened 0.45% C steel.
