What is cermet, borazon?

Rahul urkude said:   10 years ago
Cermet is combination of ceramic and metal and borazon is combination of boron and atoms of nitrogen.

Abdul said:   10 years ago
In cermet 90% ceramics and 10% metal mixture.

SS BALA said:   9 years ago
Ceramic (CER) & metallic (MET).

Borazone is nothing but boron nitride.

Nirav said:   9 years ago
Borazon = CBN = CUBIC BORON NITRIDE.

Faruk ali said:   8 years ago
CBN is the second bardness tool material. Please, anyone tell me how hot hardness temperature.

Manu said:   8 years ago
Hot hardness temperature: the max temperature upto which it can absorb without deformation.

Raki said:   7 years ago
Hot hardness is the ability of a material to retain hardness at high temperature.

Kannan said:   7 years ago
The correct answer should be A.
