Sliding Wear Behaviour and Corosion Resistance to Ringer’s Solution of Uncoated and DLC Coated X46Cr13 Steel

Abstract Sliding wear properties and corrosion resistance in Ringer’s solution of uncoated and diamond-like carbon (DLC) coated X46Cr13 steel was tested. The Raman spectra showed that the DLC film was successfully coated by plasma assisted CVD method onto the steel surface. The wear test, carried out using a ball-on disk tribometer, revealed that the DLC coating show better resistance to sliding wear and lower friction coefficient against a 100Cr6 steel ball than five times softer X46Cr13 steel. The oxidation kinetic parameters were determined by means of both the gravimetric and electrochemical method. It was found that the DLC coating markedly decreased the rate of corrosion of the X46Cr13 steel, irrespective of the corrosion mechanism involved.

Dry sliding wear properties of aluminum nitride (AlN) reinforced aluminum silicon (Al-Si) alloy were investigated by using a pin-on-disc configuration tester. In this work, different weight percentages (5 and 10 wt%) of AlN was added into the Al-Si alloys. The samples were prepared by a stir casting process via a bottom pour technique which was then aged with a T6 condition prior to the wear test. Detailed analyses on the morphologies were conducted using scanning electron microscope (SEM) with the aid of an energy dispersive x-ray analyser (EDX). Prior to the heat treatment, the distribution of hard aluminum nitride particles that surrounded the Si phase had improved the hardness of the composites by 15%. The hardness value was found to be significantly increased about 80% for aged samples compared to un-aged samples. This was mainly contributed from precipitations of Si grain and intermetallic compounds; Mg2Si and FeSiAl5 formation in the alloys. Thus, a significant increased in wear resistance up to 56% was also observed especially at the highest applied load of 70N. Surface investigation by a scanning electron microscope (SEM) revealed that a combination of abrasion and adhesion wear mechanism was dominant for both un-aged and aged samples.

Wear Properties

In today's rapidly developing automobile and aeronautical industries, numerous composites are widely used for various applications. This increases the need for continuous research and development of a number of composites. This research work investigated various volume % of cenosphere reinforced AA6063 composites which were made by stir casting method. These composites were surveilled with the help of chemical analysis and scanning electron microscopy to ensure the distribution and bonding between reinforcement and matrix. The design of experiments (DOE) was used to plan the wear tests and the wear results were obtained. The dry sliding wear behaviour of composites was studied by means of a pin-on-disc wear test machine and the results were compared with pure AA6063. The influences of critical parameters such as applied load, sliding speed were evaluated. Enhanced wear properties were observed with addition of cenospheres in aluminium alloy. Disc brake rotor was cast with optimum amount of cenosphere % using sand moulding.

Modelling And Optimization

Copper-Graphite composites have been prepared through powder metallurgy (P/M) method. 0 3 and 6 wt % of graphite particles have been added as the reinforcement to the Copper powder which forms the matrix and composites have been prepared. Microstructure of the newly prepared composites was analyzed using Scanning Electron Microscopy (SEM). Wear test was done using Pin-on-disc tribometer according to G99 standards. A linear regression Mathematical model has been developed using RSM to predict the sliding wear behavior of the composites. Optimization has been done using RSM and also based on ANOVA to find the significant parameters affecting the sliding wear.
