Composite Coating Techniques – A Review on Process Parameters and its Impact on Characterizations.

Adarsha H, Anoushka Chaturvedi, Khushbu Chopda, Nikitha Nair


Surface modification with composite coating technology is the need of the hour in most of the industries. Changing the bulk properties of the material by surface modification is one of the simplest techniques to do so, and this also avoids industrial downtime. An attempt is made in summarizing the processing techniques of developing composite coatings. The effects of coating parameters on the micro-structure, porosity, bond strength and micro-hardness have also been discussed. High velocity oxy- flame (HVOF) coating sounds to be a promising technology for the development of composite coatings.
