| Research Abstract |
The electrolytic are heating process of the sprayed coating to improve the denseness and the bonding of the deposited coating has been developed. The effect of the electrolytic arc heating conditions on layer formation was investigated, and the coating properties were examined by hardness tests, abrasive wear test and corrosion tests. The Vickers hardness of the electrolytic arc heated Ni base self-fluxing alloy coatings was HV650-700, equal to or higher than that obtained with a flame fusing sprayed coating. The electrolytic arc heated Ni base self-fluxing alloy coatings displayed superior properties, including wear resistance and corrosion resistance, compared with mild steel and stainless steel. The microstructure and bond strength has been investigated for joint of a copper to carbon steel produced by electrolytic arc heat bonding with Ni base self-fluxing alloy coatings. Joint strength of copper/steel was measured to be in the range of 440-470 MPa.
