Cylinder Head gasket

In order to optimally seal the combustion chamber, an optimal balance between engine component distortion and gas seal compression is necessary.
BrazeTec and development partner Federal Mogul Sealing Systems have developed a metal suspension which can be applied to steel layers in a contour-stable way and which acts as a blocking-layer after being brazed.
Here, the suspension is applied to the finished shaped support layers in a screen printing process.
Due to its high adhesion and corrosion-resistance, a mixture of nickel-based alloy NI 102 and a high melting point additive Ni80Cr20 was used. The working temperature is about 1050°C.
Hydrogen was used as the brazing atmosphere. The blocking-layer thickness can be varied as desired from 0.04 mm up to 0.12 mm. The brazing is carried out without flux in a continuous furnace with an inert gas.
