Potential applications of thermal spray coating for I.C. engine tribology: A Review

The IC engine has been a conventional source of producing mechanical energy for various applications. The tribopair of piston ring and cylinder liner has to work in adverse tribological conditions such as high temperature, speed and load. The wear of piston ring not only reduce the performance of the tribopair but also cause the failure of the system. The insufficient lubrication at the interface increases the tribological losses drastically. The tribological losses can be minimized by coating of some material which has superior tribological performance. The thermal spray coating can be used for providing a stable coating over the tribological surfaces. The versatile operating conditions and process parameters assist the deposition of required material to a desired thickness over the various substrate materials. The process can be used for producing the stable coating over at a faster deposition rate. The environmental friendly coating material can be used as a bled with the conventional coating material for making the process sustainable.
