Wear-Resistant Coatings Reinforced with TiB₂ Micro-Particles and TiCN Nano-Sized Particles

Abstract

A wear-resistant composite coating process with electroslag surfacing using a current-supplying solidification mould was developed. The structure and properties of coatings from flux-cored wire deposited alloys with refractory micro-particles of titanium diboride, TiB2, and nano-sized particles of titanium carbonitride, TiCN, were studied. Special features of the elasto-plastic deformation of composite alloys’constituents were studied with sclerometry.

A Production Method for Wear-Resistant Deposited Coatings Modified with TiN Particles

“…It is known that the ultrafine particles of refractory compounds in electrode deposited materials (flux-cored and composite wires, coated electrodes) increase the mechanical and working properties of arc-deposited alloys [1][2][3]. However, the refractory particles contact with the arc plasma and overheated liquid drops form on the electrode butt, which activates their dissociation process.…”

Eutectic TiB2–Ti(C,N) Alloy by SHS Method from Ti–B–C Powder Blends in a Coflow of Nitrogen Gas

“…As compared to WC-and TiC-based materials, TiB 2 -Ti(C,N) composites exhibit higher hardness and corrosion resistance at high temperatures, which makes them promising for use in cutting instruments and structural materials for aerospace and motor-car engineering [1][2][3][4]. According to [5][6][7][8], the TiB 2 -Ti(C,N) system admits the formation of the ternary 36TiB 2 -44TiC-20TiN eutectic (mol %).…”

“…According to [5][6][7][8], the TiB 2 -Ti(C,N) system admits the formation of the ternary 36TiB 2 -44TiC-20TiN eutectic (mol %). This com- pound is of especial interest in view of is ability to form (due to self-assembling [8]) a uniform eutectic structure [3,4].…”
