ThermaSiCThermaSiC is a SiC based coatingCoating where 1 µm particles of SiC are embedded in a matrix of YAG, giving a coatingCoating with high hardness and wear resistance.

ThermaSiCThermaSiC coatingCoating does not wet molten aluminumAluminum as the contact angle has been measured to be between 140 and 150° depending on coatingCoating conditions. The non-wettingNonwetting and wear-resistant properties have enabled ThermaSiCThermaSiC to work as a novel coatingCoating for the steel rollers submerged in molten aluminumAluminum for extended periods during the aluminizing of steel strips.
