The impact wear resistance of the hard coating is very important in high-temperature environment nuclear power plant. CrN and CrAlN coatings were prepared using multi-arc ion plating. abrasive was investigated at varied temperatures through a controlled kinetic energy rig, their mechanism elucidated. No extensive spalling found on surface after 104 impacts under no-sand condition. excellent ant...

The duplex treatment of AISI 420 steel samples by nitriding in a radiofrequency inductively coupled plasma (RF-ICP) discharge Ar + N2 H2 atmosphere followed CrAlN coating deposition was performed this study. influence (PN) duration (10, 20, 40, and 60 min) on the structural functional properties duplex-treated determined. A non-linear dependence kinetics found square root PN duration. thickness...
