摘要

研究了用非定域电极和镍铝混合颗粒电火花法在35钢表面沉积的Al - Ni - Fe镀层。研究了三种颗粒混合物在涂覆过程中的传质动力学。测定了镀层的相组成、显微组织和硬度。进行了腐蚀和磨损试验。结果表明，在钢表面沉积Al - Ni - Fe涂层可降低钢的自腐蚀敏感性，使腐蚀电流密度降低1.6 ~ 2.6倍，使钢的耐磨性提高3.7 ~ 6.2倍，并提高钢的耐热性。

Structure and Properties of Al – Ni – Fe Coatings on Steel 35 Obtained by Electrospark Deposition

Al – Ni – Fe coatings on steel 35 deposited by the electrospark method using a non-localized electrode and mixtures of nickel and aluminum granules are studied. The kinetics of the mass transfer of mixtures of granules of three compositions during application of the coatings is investigated. The phase composition, the microstructure and the hardness of the coatings are determined. Corrosion and wear tests are carried out. It is shown that the deposition of Al – Ni – Fe coatings on the steel can reduce its susceptibility to spontaneous corrosion, lower the corrosion current density by a factor of 1.6 – 2.6, raise the wear resistance by a factor of 3.7 – 6.2 and elevate the heat resistance.
