The invention discloses a chromium-ferrum-carbon- tungsten-nickel synthetic reaction plasma cladding powder and the preparing process thereof. With sucrose as the precursor of carbon, by carbonizing under a specific temperature, a chromium-ferrum-carbon- tungsten-nickel plasma cladding composite power coated with carbon is formed. The process is as follows: mixing the raw materials powder(except the sucrose) in accordance with the granularity requirement in proportion, wet grinding, drying the mixed slump powder, carbonizing the mixture of the dried powder and the sucrose by step, and crushing and screening the carbonized block-like substance.

The invention was involved in Ti-Ni-C alloys response spray coating complex powder and its preparation method, which belonged to the powder manufacturing craft of metal ceramic complex coating technology. Cane sugar was used as precursor of carbon and it was carbonized under definite temperature to form Ti-Ni-C alloys response spray coating complex powder, which was enclosed by material powder. The technology was: mixing the Ti and Ni power with mixture ratio ->wet grinding->drying the slurry ->carbonization step by step->breaking and screening. The method not only settled the separation of response component during the response spray powder but also the cane sugar was used as precursor of carbon so it had low carbonization temperature, high carbon purity, small pollution of process of carbonization and the high industrial feasibility. To select Ni as the metal base to reduce rather large grain TiC conglobation and increase the wear-resisting property of coating.
