Thermal Spray Thin Layer
- Category Name:
- Thin Layer
Thermal spraying is an industrial coating process that consists of a heat source (flame or other) and a coating material in a powder or wire form which is literally melted into tiny droplets and sprayed onto surfaces at high velocity.
Coating quality is usually assessed by measuring its porosity, oxide content, macro and micro-hardness, bond strength and surface roughness. Generally, the coating quality increases with increasing particle velocities.
The demands for engineering coatings are becoming more and more stringent. Environmental concerns are also being considered as an integral part of the design process. For future economic competitiveness and a lower environmental impact we must therefore turn our attention to processes that use the minimum of resources. Thermal spraying is an attractive coating technique as it offers a wide choice of materials and processes that have a reduced impact on the environment when compared to conventional plating processes.
Thermal spray coating techniques such as HVOF, flame wire spraying, flame powder spraying, arc wire spraying, plasma spraying and cold gas spraying,allow many problems of wear, corrosion and thermal degradation to be resolved by engineering the surface with tailor-made coatings.
