“…7, the wear volume loss is inversely proportional to the bulk hardness of the WC-Ni grades, in agreement with e.g. [29,32,33,41,42]. This can be attributed to more pronounced adhesion and micro-abrasion for the lowest hardness WC-Ni alloys.…”

A number of WC-Ni based cemented carbide grades with distinctive binder contents were tested with the goal to evaluate their dry reciprocating sliding friction and wear behaviour against WC-6 wt.%Co cemented carbide using a Plint TE77 tribometer and distinctive normal contact loads. The generated wear tracks were analysed by scanning electron microscopy and quantified volumetrically using surface scanning topography. The experimental results revealed one WC-Ni grade with superior wear performance.

“…The mechanical and tribological properties of these coatings can further be improved by the incorporation of hard particles [11][12][13][14], heat treatment [12,15] and dry lubricants [16,17]. Friction and wear of EN coatings have been the focus of attention to a number of researchers over the years [18][19][20][21]. The friction study of electroless Ni-P coating with a ramp apparatus concluded that coatings with high phosphorus content have higher friction coefficient than medium or low phosphorus electroless coatings [19].…”

The present paper deals with the synthesis of electroless nickel-phosphorous (Ni-P) coatings on mild steel substrate and optimization of the coating process parameters for minimum friction and wear in brine solution using Taguchi based grey relation analysis. The study is carried out using different combinations of four coating process parameters, namely, concentration of nickel source (A), concentration reducing agent (B), bath temperature (C) and annealing temperature (D) with three levels each (1, 2 and 3). The wear and friction tests are conducted with a pin-on-disk Wear & Friction Monitor. Taguchi based grey relational analysis is employed for the optimization of this multiple response problem using an L 27 orthogonal array. The optimal combination of parameters is found as A3B3C1D2 which yields an improvement in grey grade of 62 % compared to the mean grey grade. ANOVA is performed to find out the significance of the coating parameters and their interactions. Bath temperature and annealing temperature are most influential in controlling friction and wear behavior. The surface morphology and composition of coatings are studied with the help of scanning electron microscopy (SEM), energy dispersed X-ray (EDX) analysis and X-ray diffraction (XRD) analysis. It is found that Ni-P coating is amorphous (weight percentages: 91.56 % Ni and 8.44 % P) in as-deposited condition but gradually turns crystalline with heat treatment. The worn surface morphology reveals abrasive wear mechanism.

“…10 Friction and wear, being important properties of EN coatings, have been the focus of attention of a number of researchers [12][13][14][15][16][17] over the years. It is, in general, observed that the friction coeffi cient of EN coating decreases with an increase in load.…”

This paper presents an experimental study of tribological characteristics of electroless Ni-P (EN) coatings and optimisation of coating process parameters based on Taguchi method coupled with grey relational analysis. A grey relational grade obtained from the grey relational analysis is used as performance index to study the deposition of EN coating with multiple tribological performance characteristics. Experiments are carried out by utilising the combination of process parameters based on L 27 Taguchi orthogonal design with four process parameters, namely, bath temperature, concentration of nickel source solution, concentration of reducing agent and annealing temperature. It has been observed that concentrations of nickel source solution and bath temperature are the most signifi cant parameters for controlling the friction and wear behaviour of EN coating. The surface morphology, composition and wear mechanism of coatings are also studied with the help of scanning electron microscopy, energy dispersed X-ray analysis and X-ray diffraction analysis.
