چکیده
Cr2O3 and Cr2O3–SiO2-TiO2 coatings are deposited on P265GH steel using atmospheric plasma spraying. The influence of silicon oxide—titanium oxide addition the surface morphology coatings, phase composition tribological properties under non-lubricated sliding conditions investigated. SiO2-TiO2 led to formation a more uniform reduce roughness coatings. X-ray diffraction (XRD) studies indicated that both composed an eskoloite phase. friction coefficients coating 0.504 0.431 when 1 N 3 loads were used, respectively. Meanwhile, demonstrated slightly lower values similar loads. specific wear rate as-sprayed is reduced with SiO2-TiO2. It was found rates up 20 times compared substrate. This article expanded version “19th international conference physics applications” abstract.

Evaluation of tribological properties of (Ti,Al)CN/DLC composite coatings deposited by cathodic arc method.
In this study, Ti, Al and N doped DLC – referred to here after as “(Ti,Al)CN/DLC composite”- coating and pure diamond-like coating (DLC) were produced by cathodic arc deposition technique and the effects of the coating thickness on their tribological properties were evaluated. The coatings were characterized, using scanning electron microscopy (SEM), atomic force microscopy (AFM), X-ray diffrac...
متن کاملEffect of Gas Ratio on Tribological and Corrosion Properties of Ion Beam Sputter Deposited TiN Coatings
Titanium nitride thin films were grown on 304 stainless steel substrates at various nitrogen/argon flow ratios by ion beam sputtering (IBS) technique. The current research is a follow up study on the influence of gas ratio on structural and corrosion properties in the TiN coated 304 stainless steel. Film structural identification of phases was performed using X-ray diffractometry (XRD). Sca...
متن کاملThe tribological properties of Cu-Ni3Al-MoS2 composite coating deposited by magnetron sputtering
In industrial applications, most materials are exposed to wear and friction because multiple conditions are used. However, the tribological properties of these materials can be improved with different techniques. One such technique that improves the frictional property of a surface is the use of self-lubricating coatings. In this study, multicomponent coatings of nominal composition Cu-Ni3Al-Mo...
متن کاملPlasma spraying of micro-composite thermal barrier coatings
The thermal barrier coatings (TBCs) by gas tunnel-type plasma spraying exhibited ceramic-composite features consisting of a host oxide matrix ceramic with an embedded second phase material. The densities of the composite TBC were found to be higher than those sprayed with 100wt% ZrO2 or Al2O3. In the coatings produced with powder mixtures of 50wt%, the embedded splats are found to have a relati...
