Abstract The purpose of this study is to investigate the microstructure and wear resistance of plasma sprayed WC-Co- Ni coatings. WC-Co-Ni composite powders were prepared by mixing of WC powder, Co powder and a Ni-P alloy powder, followed by sintering and crushing to improve the properties of plasma sprayed WC-Co coatings. In this study, their coatings were deposited by the atmospheric plasma spraying. The evaluation of their coatings were carried out by the observation of microstructure, measuring of microhardness values, adhesion strength values and an abrasive wear test. The abrasive wear resistance of the as-sprayed WC-Co-Ni coatings was comparable with that of WC-Co coatings deposited by HVOF spraying, and besides, the properties of the post-treated WC-Co-Ni coating were comparable with those of cemented carbides.

A relative study among various types of coating materials to develop wear resistance of stainless steel has been performed. Ceramic coatings with the thickness up to 250 μm were prepared by Atmospheric plasma spray technique on the stainless steel. Two different types of coating materials such that Yttria Stabilised Zirconia, Zirconia Ceria powder were used. The influence of Ceria powder on abrasive wear was determined. It was found that the addition of Ceria to Yttria Stabilised Zirconia in a sufficient amount helped in increasing its wear resistance compared to the wear behaviour of pure Yttria Stabilised Zirconia powder. Moreover, it was found that the lesser the surface roughness of the coating layer,.

Effect Of Surface

On the example of Hadfield steel, as the most common material of fast-wearing parts of mining equipment, the effect of surface hardening by plastic deformation on their impact and abrasive wear resistance is considered. Wear test is conducted on magnetic ironstone as typical representative of abrasive and hard rock. As result of wear of initial samples with hardness of ∼200 HB and samples pre-hardened with different intensities to the hardness of 300, 337 and 368 HB, it is found that during the initial testing period, the initial samples pass the “self-cold-work hardening” stage with increase in hardness to ∼250 HB, which remains virtually unchanged during further tests; the hardness of the pre-hardened samples does not change significantly throughout the tests. It is established that the rate of impact-abrasive wear of pre-hardened samples is significantly (up to 1.4 times) lower than the original ones that are not subjected to plastic deformation, and decreases with increasing degree of cold-work hardening. Preliminary surface hardening by plastic deformation can serve as effective way to increase the service life of fast-wearing working parts of mining equipment.
