Diamond, Cubic Boron Nitride Particles Coated Tungsten, Chromium, Molybdenum Method

The present invention provides a diamond, cubic boron nitride particles coated tungsten, chromium, molybdenum method. Specific steps are as follows:

1) Clean and pollution diamond, cubic boron nitride particles into the heating chamber in a vacuum or protective atmosphere of diamond, cubic boron nitride particles are pre-heated;

2) The heated diamond, cubic boron nitride particles transported to the coating room with a vibration or blender to open as a coating material for metal carbonyl complexes of steam into the steam switch to the coating chamber input metal carbonyl complexes of steam, start vibrating or blender, using a heated diamond, cubic boron nitride brought the heat, so that the metal carbonyl complexes in diamond, cubic boron nitride particle surface decomposition, the diamond, cubic boron nitride particles are evenly coated metal surfaces layer;

3) The complete coating of diamond, cubic boron nitride particles are transported to the cooling chamber passivation passivation cooling the material or heating the coating cycle to the next one, until the desired thickness of the final passivation of the material was cooled and purified packaging.

The present invention provides a method which is capable of uniformly continuous diamond, cubic boron nitride particles embodiment of tungsten, chromium, molybdenum monolayer or multilayer composite coating, the abrasive and the bonding metal carcass reinforcement, extending diamond cubic BN life products.
