Moly Disilicide Coating - Dipping Sintering

Moly Disilicide Coating - Dipping Sintering As Follows:

molybdenum disilicide1. The graphite grinding into 15mm * 15mm * 15mm * test block, the use of CSF-1A ultrasonic cleaner to surface cleaning and drying the reserve;

2. By a certain percentage of the Si powder, water and polyvinyl alcohol slurry preparation, grinding in a ball mill 1h;

3. Using dip coated in graphite blocks approximately 500μm thick slurry. Dried at 110 ℃ for 12h, and then in a vacuum oven at 1450 ℃ processing 2h, the graphite substrate can be prepared on the SiC coating gradient;

4. By a certain percentage weighing Mo and Si powders, using the same process as above was prepared Si-Mo slurry;

5. Using a dip coating method of the slurry Si-Mo coated on the inner layer of SiC, Si-Mo by controlling the number of the SiC slurry dip-coated on an inner layer of Si-Mo different thickness precoat slurry;

6. Dried at 110 ℃ 12h, and then in a vacuum oven at 1420 ℃ resistance calcined 2h.

Prepared by the molybdenum disilicide coating properties:

1) Si-MoSi2 outer layer of the coating prepared SiC/Si-MoSi2 oxidation performance is greatly affected. Si-MoSi2 outer layer thickness of about 80μm, the coating at 1400 ℃ showed good high temperature oxidation resistance. Too thin or too thick detrimental oxidation resistance.

2) coating the surface of the coating after oxidation to form a complete, dense layer of SiO2 glass to improve oxidation resistance of the material of the root causes of
