Abstract
Growth in nanocoatings technology is moving towards implementing nanocoatings in many sectors of the industry due to their excellent abilities. Nanocoatings offer numerous advantages, including surface hardness, adhesive strength, long-term and/or high-temperature corrosion resistance, the enhancement of tribological properties, etc. In addition, nanocoatings can be applied in thinner and smoother thickness, which allows flexibility in equipment design, improved efficiency, lower fuel economy, lower carbon footprints, and lower maintenance and operating costs. Nanocoatings are utilised efficiently to reduce the effect of a corrosive environment. A nanocoating is a coating that either has constituents in the nanoscale, or is composed of layers that are less than 100 nm. For single flange track rollers, the best percentage value of Weibull distribution is 63.2% or called scale at the age of 3014.46 hours. As for the double flange track roller, the best percentage value of Weibull distribution is 63.2% or called scale at the age of 3360.04 hours. The single flange track roller and the double flange track roller have the same type of cause of failure is wear-out. However, double flange track roller reliability is better than single flange reliability. Therefore, double flange track rollers are more suitable to be applied at PT Kaltim Prima Coal than single flange track rollers.
