Ceramic Coating Processes

The thermal barrier coating is the techniques of coating in which heated or melted materials are sprayed onto a surface. The coating precursor called the "feedstock" is heated making use of an electrical, plasma, arc or chemical means. The method can offer thick coatings (roughly a thickness range is twenty micrometers to several mm, depending upon the process and the feedstock) over a massive area at high deposition rate rather than other procedures such as physical, electroplating, and chemical vapor deposition. The materials obtainable for thermal spraying include alloys, metals, ceramics, composites and plastics. They are fed in wire or powder form, heated to a semi-molten or molten state and quicker towards substrates in the shape of smaller-sized particles. Electrical or combustion arc discharge is normally used as the source of energy for such spraying. The results are made by the build-up of countless sprayed particles. The surface may not heat up considerably, perm
