| Abstract: | Chromizing layer was prepared on the surface of Ti6A14V alloy by means of double glow plasma surface metallurgy. The chromizing parameters were optimized based on orthogonal experiments, and the high-temperature oxidation resistance of as-fabricated chromizing coating was evaluated. Results show that, in terms of the thickness of the chromizing layer and its bending strength to the substrate, the optimum technological parameters are suggested as source voltage of 950V, workpiece voltage of 300 V, air pressu... |
