“…adhesive wear. This means that wear of Ni-P IManE&E 2017 4 coating in described test is a predictable process, and final, destructive phase of wear can be anticipated. In case of machine maintenance this is considered as significant advantage, as lesser probability of unexpected and unpredictable failures means easier machine maintenance.…”

“…Ni-P (nickel-phosphorus) coating manufactured with electroless, chemical reduction method can be applied to aluminum alloy substrate [3]. In contrast to electric manufactured coatings, electroless Ni-P coating can be applied not only for decorative reasons, because of better adhesion to substrate and higher resistance to abrasive wear [4].…”

Abstract.Results of tribological tests of Ni-P coating were presented in following paper. Tests were conducted with tribotester device using linear reciprocating wear test. Tribological wear test conditions, especially speed, load and sample geometry were described. Characteristics of coefficient of friction variation during wear testes were recorded. Conclusions included results interpretation especially focusing on influence of coating thickness in its properties.

“…The structure of as-plated coatings has been reported to be either crystalline or amorphous, or a mixture of both [5]. A remarkable improvement in the wear resistance of the binary coating has been reported when hard particles are incorporated [6]. Another effective method to improve the properties of these coatings is alloying.…”

The present investigation deals with the chemical deposition of Ni-P-W coating on mild steel substrate and optimization of multiple surface roughness characteristics on the basis of different coating process parameters. Three coating parameters which are varied to have the optimum condition are concentration of nickel source, concentration of reducing agent, and concentration of tungsten source. Five different roughness parameters, namely, centre line average (R a ), root mean square roughness (R q ), skewness (R sk ), kurtosis (R ku ), and mean peak line spacing (R sm ) are considered. Weighted principal component analysis (WPCA) method is adopted to convert the multiple-response problem into a single performance index and Taguchi L 27 orthogonal array is used. ANOVA is performed to find the significance of the each coating process parameters and their interactions. The EDX analysis, XRD analysis, and SEM are performed to study the composition and structural aspects.

“…The traditional electroless composite coatings have been prepared by adding micro-meter particles to an electroless bath such as SiC, BN, PTFE, diamond [7]. Newly developed Ni-P alloy coatings have been recently reported by the introduction of a third element such as tungsten to form ternary Ni-P-W [8][9][10][11]. Published data showed that inclusion of tungsten in binary Ni-P deposit positively affects the deposition rate, composition and deposit properties such as hardness, thermal stability, wear, corrosion resistance, and melting point [10].…”

This paper deals with the synthesis of electroless Ni-P-W coatings on mild steel substrate followed by furnace-annealing process. Corrosion behaviors of the coatings after heat treatments at various annealing temperatures are evaluated by potentiodynamic polarization test using 3.5% sodium chloride solution. The electrochemical parameters, that is, corrosion potential and corrosion current density, are optimized for maximum corrosion resistance using Taguchi-based grey relational analysis, considering four coating parameters, namely, concentration of nickel, concentration of reducing agent, concentration of tungsten, and annealing temperature as main design factors. The optimum combination of these four design factors is obtained from the analysis. The analysis of variance reveals that the concentration of tungsten source and annealing temperature play the most important role on the corrosion performance of the coating. Effects of the operating parameters on microstructures, in terms of porosity formation, crystallization, phase transformation, grain growth, are investigated using SEM, EDX, and XRD techniques.
