Molybdenum alloy coating infiltration prepared method as follows:
1.Weight ratio according to the following ingredients and preparation of coatings.
Material powder: 100.
Containing silica: 40 ~ 90% of chromium powder: 5 ~ 30%, iron: 5 ~ 30%
Powders can also be made according to the above ingredients and matching pre-alloy, and then ground to a powder.
Nitro varnish: 10 to 30 grams of ethyl acetate: 100 to 150 ml
2.In the 0.6 ~ 1atm under a spray pressure of the paint coating to the surface of the part.
3.Into the drying oven.
4.Then into the vacuum of 10-3 to 10-4 mm Hg temperature vacuum heat treatment furnace, furnace temperature should be controlled by the CCP near or above the melting point material powder. For 3 to 30 minutes.
5.Natural cooling in the furnace after completion of infiltration system.
