High-temperature tribological properties of Ni-P alloy coatings processed by electro-brush plating on 20CrMo steel have been investigated. A ball-on-disc configuration was employed and 4 mm diameter Si 3 N 4 balls were used as static counterpart. All the wear tests were carried out at 450°C for 180 min without lubricants. The electro-brush plating Ni-P coating is amorphous in as-deposited condition, and it becomes polycrystalline with the formation of Ni and Ni 3 P after heat treatment at 450°C for 1 h. The friction coefficient of the Ni-P coating is just 50% of that of the 20CrMo steel at the friction temperature of 450°C. A mild adhesive wear mechanism was found for the electro-brush plating Ni-P coating tested at 450°C, whereas for the 20CrMo steel at the same temperature a mixed adhesive and abrasive wear mechanism was observed.

This paper have studied the high temperature frictional wear properties of Ni-P coatings on 20CrMo steel manufactured by electro-brush plating. A ball-on-disc configuration with no lubricants was employed and 4 mm diameter Si3N4 ball was used as static counterpart. The results showed that with the coating time increased from 0 to 24 minutes, the overall average friction coefficient and the mass worn loss of specimens were both declined in the wear test at 450 oC for 180 minutes. The wear became slighter as the coating time increased. When the coating time were 0, 6, 12 and 18 minutes, the main wear form of samples were deep microscopic plough cutting and spalling failure. As the coating time increased to 24 minutes, its main wear form were shallower microscopic plough cutting, almost no spalling failure.

Abstract. Deterministic electroplating repair is a novel method for rapidly repairing the attrited parts. By the qualitative contrast and quantitative comparison, influences of the current density on performances of the chrome-plated layer were concluded in this study. The chrome-plated layers were fabricated under different current densities when the other parameters were kept constant. Hardnesses, thicknesses and components, surface morphologies and roughnesses, and wearability of the chrome-plated layers were detected by the Vickers hardness tester, scanning electron microscope / energy dispersive X-ray detector, digital microscope in the 3D imaging mode, and the ball-milling instrument with profilograph, respectively. In order to scientifically evaluate each factor, the experimental data was normalized. A comprehensive evaluation model was founded to quantitative analyse influence of the current density based on analytic hierarchy process method and the weighted evaluation method. The calculated comprehensive evaluation indexes corresponding to current density of 40 IntroductionDeterministic electroplating repair is a new and practical method for rapidly repairing the attrited parts, which is based on the deterministic surfacing theory [1] and electroplating technique [2,3]. Schematic diagram of the deterministic electroplating repair system is shown in the figure 1. Original profile of the attrited part is obtained by three-coordinate measuring machine. Through subtracting the expected shape from the original profile, theoretical distribution of the optimal deposition layer is calculated. The electroplating solution is sucked from the container to the nozzle head by the peristaltic pump and is absorbed back to the container by the atmospheric pressure generated from the vacuum ejector. Through controlling concentration of the electroplating solution and the current density between the anode and the attrited part, shape of the deposition function and its efficiency can be kept steady. Distribution of the dwelling time can be achieved by the Fourier transform and convolution operation based on the theoretical distribution of the optimal deposition layer and the deposition function [4]. By controlling movement of the nozzle head which is installed on the three-dimension (3D) motion platform according to distribution of dwelling time, the attrited part can be deterministically repaired. Different from electro-brush plating [5] and electro-bath plating [6], parameters in the deterministic electroplating repair should be accurately controlled, because stability and veracity of the deposition
