AbstractFlame thermal spraying technology was used in the production of 25% zirconia composite material with 25% alumina particle with binder material of 50% Al-Ni alloy base on 316L alloy steel base, after preparation the base surface with a method of roughing the granular. Spraying was carried out using a spray distance (12,14,16,18,20) cm. Hardness tests were carried out on the composite material to study the effect of changing spray distance on the properties of the resulting layer. The thermal treatment was performed on the samples at (850,950,1050,1150) for an hour. The results of the tests confirmed that the best spraying distance (16 cm) and the thermal treatment (1050 ) have a significant effect on improving the hardness of the layers of the composite material.
