PTA surfacing of metal matrix composites
Original language description
Plasma transfer arc surfacing is very perspective technology, which is currently used to create layers with special properties such as corrosion resistance, wear resistance or resistance against high temperatures. Perspective way of increasing wear resistance of Nickel based coatings is combining it with hard ceramic particles using plasma transfer arc surfacing technology. This study deals with creating and characterization of metal matrix composite based on Nickel 625 type alloy with B4C. Metal matrix composite (MMC) with B4C was created by co-feeding Nibasit 625 – P/LFe® and B4C powder into a melting pool. The two powders were mixed together in two ratios. B4C particles have been dispersed in deposited coatings, they have partially dissolved in Ni-based matrix and formed different microstructural formations such as carbides and borides. Dissolution of B4C particles ensures good cohesion with matrix. Coatings are well metallurgically connected to the substrate – AISI 304 corrosion resistant steel. Coatings were examined in terms of microstructure. In macro-view perspective Vickers hardness has been measured and abrasion resistance test using dry sand/rubber wheel according to ASTM G65 standard has been performed.
