New cost-efficient technology combining pulsed arc evaporation (PAE) and electro-spark deposition (ESD) in vacuum was developed implemented to coat Ti with two-layer WC/a-C coating a single technological run using the same WC-6%Co electrode. A thick bottom ESD layer (70–90 μm) composed of β-Ti (~70%), β-(W,Ti)C1-x small amount α-Ti. thin upper PAE had two sublayers (3.2 1.6 μm thick) sequentially deposited an Ar C2H4 atmosphere. Both nanocomposite, nearly amorphous structure, which...
Coatings with a high amount of MAX phase were obtained onto Ti substrate using the pulsed electrospark deposition (PED) technique and Cr2AlC electrode material (ЕМ). The structure formation coatings generated at different modes studied. It was found, that layer titanium carbide formed during initial stage interface as result chemical reaction between which further acts diffusion barrier.
Abstract The composition and structure of coatings deposited with nano‐ microstructured electrodes WC‐8% Co onto Ti substrates were characterized by XRD, XPS, EPMA, SEM, SIM. Physical chemical processes taking place at the contact surface electrode substrate during electrospark deposition are considered. Under optimized conditions ( E = 0.13 J), a nanostructured provides fine‐grained exhibiting higher hardness, improved wear resistance, lower friction coefficient (compared to VK8‐based...
Abstract In this work, we explored the effects of electrode material constituents and structure on composition, tribological properties, roughness electrospark deposited coatings. Nanostructured (WC grain size below 0.1 µm) microstructured 1–2 electrodes based 92% WC–8% Co composition were used to produce coatings titanium alloy substrates. Fine‐pored graphite (FPG) carbon–carbon fiber composite (CCFC) additionally for surface smoothing as a finishing operation. The use nanostructured...
