A New High-performance Thermal Spray Coating—— Yttrium Coating

Yttrium Coating has the properties of being high temperature resistant, corrosion resistant and abrasion resistant. The particle size of yttrium is nanometre.  So far, the main applications of nano yttria coating is to protect the plasma etching equipment from being corrosive. While the equipment is working, the gas releases and it will dash and corrode the essential components of the equipment. Therefore, thermal spraying coating is necessary for the machine to protect it from being damaged. With this coating, it will help to extend the machine’s life length and improve the working precision. 

Alumina and zirconia are the frequently used as materials for corrosion resistant thermal spraying coating. However, since these two kinds of materials could not keep up with the demands of technological improvement, they will be replaced by yttrium coating gradually. 

Yttria coating’s melting point is higher than 2400℃, which is competent to be high temperature resistant for being as the thermal spraying coating. 

For precise, vulnerable and high valued parts of the machines, yttria coating can also provide the functions of protecting and repairing to prolong service life. In the near future, yttria coating will be applied in various fields of the innovations of technology. 

Under the strict processing procedures, we are able to offer our clients nano yttria coating materials reaching the international standard. We are dedicated to offering our customers with high quality products.
