Abstract:

Purpose – The purpose of this paper is to determine the appropriate conditions for the chemical deposition of Ni-P-Al2O3 composite coatings, deposited on metalic matrix.

Design/methodology/approach – Auto catalytic reduction of Ni in nickel sulfate and sodium hypophosphate bath, including 10 percent volume fractions of nanodispersive Al2O3 particles is treated in the alloy steel 100Cr6. The wear resistance and friction coefficient of the coatings are determined using tester T-01M, a ball-disc tester for mitigated solid friction conditions, in model lubricants: oil bases, oil bases with antiwear additives AW.

Findings – The analysis of the properties of the Ni-P-Al2O3 deposits confirms that the presence of the dispersion phase of aluminium oxide determines the coating wearability.

Practical implications – The paper presents some indications of proper selection of antiwear coating generation methods (their parameters and conditions).

Originality/value – Investigations show that tribocatalytic effect of nickel coatings influence the intensity of antiwear layers generation in zinc dialkyldithiophosphates (ZDDP) tribochemical interaction in model lubricants and that tribochemical, adsorption, and reaction-diffusion effect of ZDDP, decided on great effectiveness of generated antiwear surface layers, which was confirmed by the results of tribological investigation.
