Influence of Titanium-Coated Diamond Content on the Microstructure and Wear Resistance of Ni60A Laser Cladding Coatings
In this paper, the single-factor variable method is used to analyze the influence of titanium-coated diamond on nickel-based coatings on titanium alloys. The thermal stress change, phase composition, element distribution, microhardness and wear resistance mechanism of the coatings are investigated. The cladding layer is mainly composed of diamond, TiC, Cr7C3, NiTi2 and other phases. When the content of Ti-coated diamond is 4%, the grain size is significantly reduced, and the microhardness of the cladding layer reaches 68 HRC. The cladding shows little wear; the wear coefficient is 0.21, and the wear volume of the friction pair (ZrO2 ball) is 1.29 × 10−4 cm3. The results show that adding 4% Ti-coated diamond to the coating materials can reduce the crack sensitivity between the coating and the substrate, and a nickel-based diamond coating with good performance can be prepared.
