Production Method of Chromium Light Weight Aluminum Carbide Cr2AlC Powder:
Powder Metallurgy process:
Powder metallurgy is a commonly used method to produce chrome-aluminum carbides. Mix chromium, aluminum, and carbon powder and then sinter it at high temperature to form chrome-aluminum carbide material. The specific steps are as follows:
(1) Preparation of raw material powder: the metal elements or alloys of chromium, aluminum and carbon are atomized or mechanically crushed to obtain the powder of the required particle size. Preparing raw material powder includes batching, melting, atomization, crushing and screening.
(2) Mixed powder: chromium, aluminum and carbon powder are mixed in proportion to form a uniform mixed powder. The uniformity of the mixed powder directly affects the final product's performance. High-energy mixing, ball milling and other methods can be used to obtain better mixing effects.
(3) Pressing molding: the mixed powder is loaded into the mold and pressed under high pressure. During the pressing process, pressure and temperature should be controlled.
(4) High-temperature sintering: After pressing, the prefabricated parts are put into a high-temperature furnace for sintering. During the sintering process, a chemical reaction occurs between the elements in the mixed powder to form chrome-aluminum carbides. Sintering temperature and time are the key factors affecting the properties of the final product.
