AbstractThermal spraying technique was employed for coating low alloy steel specimens that have been used in a derrick oil well frames.
Two types of ceramic materials were used as a coating material and two groups of steel samples were prepared for coating process.
The first group was coated by zirconia while the second group was coated by alumina. Ni-Al composite powder was used forbonding the coating material on the substrate surface of the steel specimens.
The hardness, adhesion strength of the coating layers as well as wear rateswere studied for the two steel group samples and compared with as received steel.
The results showed an increase in the mechanical properties with a decrease in wear rate values for coated samples as compared to those of uncoated samples.
