2+Intermediate reaction.Carbanion is often used as the carbon source of fused salt galvanic deposit carbide.In the present invention, owing to do not have carbonate in the fused salt, therefore forming the required carbon source of titanium carbide can only be from graphite anode.Experimental result shows that graphite anode has suffered comparatively serious corrosion in the pulse electrodeposition process, and obviously, graphite can form some carbonaceous products with molten salt react ion in this process.These carbonaceous products are reduced into carbon at stainless steel surface, and form titanium carbide with the titanium reaction.
Beneficial effect of the present invention:
The industrial the most frequently used method of carbide coating for preparing has chemical vapour deposition, physical vapor deposition and thermospray.Physical vapor deposition can carry out under the condition more much lower than chemical vapour deposition temperature, but lower substrate temperature also may cause the bonding force of coating and matrix to descend; Thermospray can prepare thicker carbide coating, but coating porosity is high.The present invention adopts the method for fused salt galvanic deposit to deposit, and does not need main equipment and precious materials, and is with low cost, simple to operate.Without the need for evil gas, do not produce objectionable impurities, so present method is environmentally friendly in the reaction process yet.Fine and close with the titanium carbide coating that present method obtains, performance is good.
