自熔耐磨合金喷焊层具有较高的硬度、较好的耐磨性、及耐腐蚀性和抗高温氧化性能等优点,已被冶金、化工、机械等行业广泛地应用。随着各行各业对自熔耐磨合金热喷焊的广泛采用,切削加工这个矛盾也日益突出。目前被大量采用的粉102镍基、粉102铁镍基、G111镍基、G112镍基、Ni60、钴包碳化钨、NiWC35碳化钨弥散型、粉105(粉102+50％WC)镍基碳化钨等自熔合金及氧化铝喷镀层不但具有高硬度,同时,为了降低合金的熔点,并使其基体强化,提高合金硬度,加入了一定
Self-fluxing wear-resistant alloy spray coating has high hardness, good wear resistance, and corrosion resistance and high temperature oxidation resistance, etc., has been metallurgical, chemical, mechanical and other industries widely used. With all walks of life on the self-fluxing wear-resistant alloy widely used in thermal spray welding, cutting the conflict has become increasingly prominent. At present, powder 102 nickel-based, powder 102 iron-nickel-based, G111 nickel, G112 nickel, Ni60, cobalt coated tungsten carbide, NiWC35 tungsten carbide dispersion, powder 105 (powder 102 + 50% WC) nickel- Tungsten and other self-fluxing alloy and alumina sprayed layer not only has high hardness, at the same time, in order to reduce the melting point of the alloy, and its matrix to strengthen and increase the hardness of the alloy, joined a certain
