Fibre-reinforced polymer composites have begun to replace the conventional monolithic materials in the recent years as a result of better specific strength and enhanced characteristics. The present work has put forward an attempt to study the dry-sliding wear behaviour of CFRP composites followed by implementation of Taguchi-GRA combinatorial approach for the two output responses namely, wear and frictional force. Load (L), sliding distance (D), sliding velocity (S), and percent of fibre reinforcement (R) are considered as input conditions and the experiments were planned using design of experiments. In addition, Principal Component Analysis (PCA) has taken into consideration for the weights calculation in GRA. An elaborate study on the implementation these methodologies on the combined behaviour of wear and frictional force has been presented. Furthermore, ANOVA data is analysed, it appears that both the load (L) and the percent reinforcement (R) has greater effect towards the wear behaviour. A detailed discussion on wear mechanism has also been presented with a support of SEM morphology.

“…The properties of the metal-cutting tool are also modified [14], which increases its functional properties. High-speed deposition of WC-Co coatings, which ensures their high wear resistance, was investigated in [15]. Wear of hard coatings under dry friction containing tungsten, chromium and cobalt is considered in [16,17].…”

This article deals with laser treatment of plasma spraying of PG-CP4 powder on steel 40H13. A multi-factor model is obtained that relates the friction coefficient of the coating to the radiation power W, the longitudinal feed of the laser beam Spr, and the distance L from the protective glass of the laser head to the sample’s surface. The model allows you to control the modes of laser processing, in order to reduce the friction coefficient of the coating. The greatest influence on the friction coefficient is exerted by the longitudinal feed Spr of the laser beam, followed by the radiation power W and the distance L. A multi-factor model of the friction coefficient of uncoated 40H13 steel treated under the same conditions as coated 40H13 steel is also established. Comparison of the two variants showed that of all the samples providing reliable adhesion of the coating to the substrate, the greatest reduction in the friction coefficient (by 30.2 %) was achieved at W = 5 kW, Spr = 25 mm/s and L = 85 mm. The results of the research are recommended for use in enterprises that implement the processes of plasma and laser processing of materials, as well as in design organizations that develop modern laser systems.

“…The results revealed that the interference structure of the coating depended on the morphology of substrate surface [15]. Mild steel pins coated with WC-12%Co displayed three times higher wear resistance than uncoated mild steel pins [16]. WC particles of range 5 % to 30 % was mixed with Cu particle and the mixture was made as coating on copper surface by solid-state sintering.…”

Pure copper was coated with Tungsten Carbide-Cobalt (WC12%-Co) using Detonation-Gun technique. A coating thickness of 541 µm was obtained and the hardness of WC-Co coated copper surface was 5.2 times greater than the hardness of uncoated surface. The wear properties of coated copper were investigated using pin-on-disc tribometer, where the WC-Co coated copper exhibited higher wear resistance than uncoated copper. Dry sliding wear properties of WC-Co was analysed using Response Surface Methodology by considering the parameters load (10, 20, 30 N), sliding velocity (0.75, 1.5, 2.25 ms-1 ) and sliding distance (750, 1250, 1750 m). The results indicated an increase in the wear rate with increasing load and velocity, whereas the increase in the distance showed minimal increase in wear rate. The worn surfaces were analysed using Scanning Electron Microscopy to understand the wear mechanism. The result from the presented experiment may find its application in clutch selector fork of automobile transmission and bearings.
