Abstract
Abstract Twin Wire Arc Spray Coating (TWAS) is thermal spraying technique that has been widely adopted in many industries due to its flexibility, and cost effectiveness in producing superior quality of coating. The demand of high-technology industries and the availability of new advanced materials have generated major advances in this field. The TWAS thermal spray process has been utilised in many industries for coating purpose on components to protect against wear, heat and corrosion, and also to build up worn components. In this study, Iron-Chrome based metal coating is used to increase the lifetime of pump impeller from AISI 304 stainless steel. The addition of nickel in the process is carried out to improve adhesive properties. A combination of NiAl and FeCrBSiMn on substrate is conducted in the experimental work to assess the coatings properties. Investigations were carried out on the effect of stand-off distance (100, 200, 300, and 400 mm) and compressed air pressure (3, 4, and 5 bar) on coating properties including coating thickness, hardness, wear resistance and bond strength (adhesive coating). The result shows that coating thickness tend to increase with increasing stand-off distance and compressed air pressure. The results reveals that there is a strong correlations between the coating thickness, hardness, wear resistance, bonding strength (adhesive coating) in coatings properties.KeywordsAdhesive coatingPump impellerTWASWear resistance
