Structure-Phase Condition and Tribological Properties of Coatings Based on Self-Fluxing Nickel Alloy PG-12N-01 After Laser Surfacing

Some parameters of laser surfacing of self-fluxing nickel alloy PG-12N-01 are considered. Different structures containing a low-melting γ-Ni – Ni 3 B eutectic and a γ-Ni – Cr 3 C 2 eutectic that crystallizes at a higher temperature and forms the strength skeleton of the coating may form depending on...

Zusammenfassung:Some parameters of laser surfacing of self-fluxing nickel alloy PG-12N-01 are considered. Different structures containing a low-melting γ-Ni – Ni 3 B eutectic and a γ-Ni – Cr 3 C 2 eutectic that crystallizes at a higher temperature and forms the strength skeleton of the coating may form depending on the rate of the surfacing. The effect of the rate of the surfacing on the wear resistance of the coating and on the coefficients of dry friction are determined.
