(1) its material is wear-resisting, high temperature resistant, and rust resistance is poor.
(2) it because of the material that it is used, determines that thermal stress, transformation stress and the frictional force of its alternating hot and cold are poor, is easy to produce
Heat fatigue crack causes brake disc to fail because of heat fatigue cracking and excessive wear.
Summary of the invention
The invention aims to solve the problems, such as that the heat resistant and wear resistant performance of existing brake disc is to be improved, and provide one
Kind has the brake disc of tungsten carbide chromium-base alloy ceramic coating.
It is the thermal spraying on the rubbing surface of brake disc that the present invention, which has the brake disc of tungsten carbide chromium-base alloy ceramic coating,
There are tungsten carbide chromium-base alloy ceramic coating or WC coating, the constituent and hundred of the tungsten carbide chromium-base alloy ceramic coating
Divide content: 86wt%WC, 10wt%Co and 4wt%Cr.
The present invention prepares ceramic coating using hot-spraying technique technology, and according to standard GB/T/T19823-2005 rule
Fixed, on common brake disc (HT250) organism material surface, one layer of manufacture contains tungsten carbide cobalt chrome ceramal rubbing surface, makes it
Reach wear-resisting, high temperature resistant, anti-corrosion, acid and alkali-resistance, oxidation resistant purpose, ceramic layer will not generate " heat fade " in certain temperature
The phenomenon that, it can be worked normally in thousand degree of hot environments, the service life of brake disc can be extended, improve brake and safety
Can, it is such as proper use of lifelong without replacement.Material is saved in the fabrication process, it is energy saving, promote environmental protection.
