镍基合金中常用作喷涂材料的主要为镍铬合金。镍铬合金具有较好的抗高温氧化性能，在800-1100℃高温下具有优良的抗起皮,耐酸、耐碱，是目前应用最广泛的热喷涂份。它还能耐水蒸气、二氧化碳、一氧化碳、氨、醋酸及碱的腐蚀。主要应用于高温条件下的钢铁、低合金钢的保护层。也可作碳化物涂层的。

Nickel base alloys commonly used for coating materials mainly for the nickel chromium alloy .Nickel-chromium alloy good high temperature oxidation resistance. excellent in 800-1000degrees high temperatures. acld-proot. Alkali resistance. is currently the most widely used hot spraying powder. It’s also resistance to water vapor. Carbon dioxide. Carbon  monoxide. Ace lie acid. Alkali corrosion. Steel is mainly used in high temperature conditions. The covering layer of alloy steel and carbide coating binding phase at low temperature.
