摘要

A variety of metallic and ceramic coatings are available to protect metallic surfaces from high temperature, wear, and corrosive environments. These coatings are applied by one of many commercially available thermal spray techniques. In Saudi ARAMCO, high velocity oxygen fuel (HVOF) spraying technique is widely used to enhance erosion and corrosion resistance of steel surfaces and frequently used to repair worn away parts and equipments; which will improve availability and reduce operational cost. There are several setting parameters that can be adjusted by the applicator which can affect the performance of the applied coatings among which the powder feed rate and the spray distance are of prime importance. The aim of the present study is to examine the influence of varying powder feed rates and spray distances on nickel-based alloy powder coatings (Diamalloy-1005) applied on steel substrates using HVOF.; Four different coatings were produced employing low (5 lb/hr) and high (20 lb/hr) feed rates each sprayed at a spray distance of 9 and 12 inches.
