Design and enhanced high temperature wear performance of laser clad Co matrix coatings containing NiCrAlY and TiC over a wide temperature.

This research aims to design a high-temperature wear resistance cobalt-based coating of hot-end parts as protective coating. The cobalt-based matrix coatings were reinforced by NiCrAlY and different contents of TiC (6.0, 8.

Effect of Ni, W and Mo on the microstructure, phases and high-temperature sliding wear performance of CoCr matrix alloys.

CoCrNi, CoCrW and CoCrMo alloys were fabricated by powder metallurgy technology. The effect of nickel, tungsten and molybdenum, as alloying elements, on the microstructure, phase, mechanical and high-temperature tribological properties of CoCr matrix alloys were systematically studied. The wear and friction behaviors were investigated from room temperature (23 °C) to 1000 °C.
