Direct sintered silicon carbide is resistant to chemical corrosion, has a high max use temp and high hardness—ideal for armor and other corrosive applications.
One way to eliminate this damage to parts is to presinter the carbide preforms before drilling, and then grinding away .030in of the surface layer following drilling operations. This procedure helps prevent 'blowout' or 'flaking' around the hole during the sintering process due to the stresses produced by drilling the powder with worn ...
