Diamond-Like Carbon Coating Applied to Automotive Engine Components

Effect of bias voltage on structural and mechanical characteristics of diamond-like carbon thin film applied by ion beam deposition

This study, investigates the effect of bias voltage on structural changes of diamond-like carbon thin film created by ion beam deposition is investigated. For this purpose, the bias voltage in the values of 0 V, -50 V, -100 V and -150 V on the AA5083 aluminum alloy was considered. Raman spectroscopy was used to evaluate structural. Influence of the bias voltage on the thickness and roughness of...

Diamond-like carbon coating under oleic acid lubrication: Evidence for graphene oxide formation in superlow friction

The achievement of the superlubricity regime, with a friction coefficient below 0.01, is the Holy Grail of many tribological applications, with the potential to have a remarkable impact on economic and environmental issues. Based on a combined high-resolution photoemission and soft X-ray absorption study, we report that superlubricity can be realized for engineering applications in bearing stee...

Study of the Effect of Substrate on 3D Surface Roughness in Diamond-Like-Carbon Coating Process

This paper presents an experimental platform which is used to study the effect of DLC coating on surface roughness. Variety of experiments is conducted and the effect of variation of the coating process parameters and type and combination of sub layers on the surface roughness of the coated part is discussed.

Failure Investigation Report on Different Components of an Automotive Engine

This paper presents an investigation report of different components failure which affect the performance of an automobile engine. The premature breakage of a four cylinder diesel engine block, crankshaft, camshaft, crankshaft bearing, camshaft bush, engine oil pump was reported. It is found that the failure of each component having the same reason for its failure as reported from different plac...
