What is Plasma Spray?

What is Thermal Spray?

Thermal spray is a coating technique that creates a practical floor to improve the overall performance of a low value substrate or component. There are many different types of thermal spray techniques, but all require the deposition of finely split metallic or non-metallic substances on a substrate while they are molten or semi-molten. Thermal spray may be applied to almost any type and form of material, which is why it is used all over the world.

What is Plasma spray?

Plasma spray is a thermal spray coating approach used to supply a superb coating with the aid of using an aggregate of excessive temperature, excessive strength heat source, a quite inert spraying medium, often argon, and excessive particle velocities.

Plasma is the word used to describe a fuel line that has been heated to such a high degree that it ionizes and becomes electrically conducting.

The use of plasma spray coating creation enables the spraying of virtually any metal or ceramic onto a wide range of substances with excellent bond energy while reducing substrate distortion.

Structure of plasma spray guns?

Plasma spray guns are made from cathodes and anodes that are negatively and positively charged. Plasma gases such as hydrogen or argon move toward the anode and across the cathode. Through the high-voltage discharge, a DC arc is formed between those sites. Because the gas is heated to extreme temperatures, plasma is formed.

The plasma is then directed downward and out of the gun's end tip. It is at this point in the plasma coating process that the gun is ready to use. The plasma spray gun is water-cooled, which eliminates overheating problems.

Application of plasma spray?

Below are some examples of industry sectors making use of the Plasma spray

l  Aerospace

l  Automotive engineering

l  Biomedical

l  Chemicals and nuclear industries

l  Electronics

l  Glass wear, iron and steel

l  Household appliances

l  Marine engineering

l  Mechanical engineering

l  Nuclear industries and chemicals

Plasma spraying is used to apply ceramic, cermet, and metallic coatings in various industrial sectors. These coatings are designed to provide protection against wear and corrosion or to provide functional properties such as thermal insulation or biocompatibility.
