“…The wear and frictional behaviour of metals has been described in a number of research works. But there's still a need to comprehend the metal behaviour in many tribological contexts [1][2][3]. Studies on the tribological characteristics of several metal types have been published recently, including as brass, aluminum, and steel grades.…”

The present paper aims at the results of an experimental examination of hybrid metal matrix composites using stir-casting technique.Aluminum alloy (Al 6062) samples reinforced with Tungsten Carbide (WC) and Molydedneum diSulphide are given. 2wt.% , 4wt.%,6wt.% of MoS2 and 3 wt.%, 6 wt.%, 9 wt.% tungsten carbide were mixed together with the aluminum alloy to create the hybrid composite. The tribological aspects of aluminium composites were studied using Pin on disc Method under wet sliding condition.Testing the hybrid composites' hardness revealed that raising the weight percentage of tungsten carbide might raise the hybrid composites' hardness. To examine the wear behavior of hybrid composites, the Taguchi method was utilized in the design of experiments (DOE) approach. The factors that were found to affect wear rate included load, sliding speed, and reinforcing percentage of WC and MoS2 are the most influencing parameters.

“…[5][6][7] Hardfacing is a metal deposition process where harder or tougher substrate materials are deposited on relatively softer base materials to increase the service life of components working in harsh conditions like high temperature, heavy wear, and corrosion. 8,9 The primary basis of applying hardfacing is to impart wear and corrosion resistance to metal surfaces by providing a hard substrate layer. 10 Some of the application areas of hardfacing include extruding machine screws, valves, valve seats of internal combustion engines, accessories for ships, petroleum equipment, power generation, cutting tools, equipment for mining, crushing, rolling, road building, tunneling, molds, forging dies, parts for nuclear plants, parts for chemical plants and many more.…”

Critical equipments of process and heavy engineering industries are prone to significant wear due to intense service conditions. Uneven and uncontrolled wear causes significant changes in dimensional and geometrical accuracies of the part surfaces, which adversely affect the parts’ functionality and service life of these parts. Shorter service life of these equipments and subsequent replacement of the same is one of the serious economic concerns. Hardfacing or hardsurfacing is comparatively an advanced metal deposition technology to deposit a hard and complex metal substrate layer on simple and softer base material surface. This process is gaining popularity at commercial level due to its unique capabilities to develop superior wear, corrosion, and impact resistance properties on worn out parts and offer huge economic advantage as substitute to costly replacement. The primarily aim of this study is to present a comprehensive review of the work done on the probable candidates for deposition materials, and summarize the influence of various process parameters on hard-faced surface characteristics. The critical issues like dilution, debonding, and residual stresses have been discussed for multi-layered hardfacing for iron-, nickel-, and cobalt-based hardfacing materials. The secondary aim of this study is to address practical issues such as selection of proper combination of base-substrate material, to understand the response characteristics of ‘plasma transferred arc hardfacing (PTAHF)’ process to minimize the de-bonding, dilution, and residual stresses and finally to improve quality of hardfacing practice.

“…Currently, it can be said that there are few published works that report microstructural aspects of SPS-sintered NiCrSiBC alloys. Thus, the current literature basically brings studies of these alloys deposited on steel substrates, which often analyze the effect of Fe dilution on the microstructure of the alloy [17]. In this way, this work intends to show that it is possible to sinter the colmonoy alloy by the spark plasma sintering (SPS) process, and consequently contribute to future studies on the possibility of sintering the colmonoy alloy on a stainless-steel substrate.…”

Nickel-based alloys of the NiCrSiBC system (colmonoy alloys) are normally deposited on stainless-steel substrates for coating applications, once they present high resistance to wear and corrosion at high temperatures. Typically, deposition occurs through welding processes, such as PTA (plasma transferred arc) or laser cladding. This study mainly aims to evaluate the effectiveness of the spark plasma sintering (SPS) process through the evaluation of the sintered body density, and structural and microstructural analysis of the Colmonoy-5. SPS sintering occurred at 900°C under 50 MPa for 15 minutes. Powder morphology was evaluated by confocal microscopy. The sintered samples were evaluated according to their density (Archimedes’ method), phase composition, microstructure, and hardness (Vickers hardness). Results showed that the Colmonoy-5 alloy can be effectively produced through SPS sintering, reaching densification above 90%. Microstructural analysis showed that there was the formation of hardening phases, such as borides and chromium carbides. The same phases are found in colmonoy alloys deposited on the stainless-steel substrate.
