“…Under these conditions, ductile materials are more easily deformed and thus will have a lower erosion resistance [23]. The same conclusion was made by Hussainova et al [46], but for hardmetals prepared by conventional powder metallurgy sintering, not thermally sprayed hardmetal coatings.…”

The tribological properties of part surfaces, namely their wear resistance and friction properties, are decisive in many cases for their proper function. To improve surface properties, it is possible to create hard, wear-resistant coatings by thermal spray technologies. With these versatile coating preparation technologies, part lifetime, reliability, and safety can be improved. In this study, the tribological properties of the HVOF-sprayed coatings WC-17%Co, WC-10%Co4%Cr, WC-15% NiMoCrFeCo, Cr 3 C 2 -25%NiCr, (Ti,Mo)(C,N)-37%NiCo, NiCrSiB, and AISI 316L and the plasma-sprayed Cr 2 O 3 coating were compared with the properties of electrolytic hard chrome and surface-hardened steel. Four different wear behavior tests were performed; the abrasive wear performance of the coatings was assessed using a dry sand/ rubber wheel test according to ASTM G-65 and a wet slurry abrasion test according to ASTM G-75, the sliding wear behavior was evaluated by pin-on-disk testing according to ASTM G-99, and the erosion wear resistance was measured for three impact angles. In all tests, the HVOF-sprayed hardmetal coatings exhibited superior properties and can be recommended as a replacement for traditional surface treatments. Due to its tendency to exhibit brittle cracking, the plasma-sprayed ceramic coating Cr 2 O 3 can only be recommended for purely abrasive wear conditions. The tested HVOF-sprayed metallic coatings, NiCrSiB and AISI 316L, did not have sufficient wear resistance compared with that of traditional surface treatment and should not be used under more demanding conditions. Based on the obtained data, the application possibilities and limitations of the reported coatings were determined.

“…He stated that reactive sintered cermets offer excellent erosion wear resistance because of good micro structural features. 18 Celotta et al in his investigation observed the erosion behaviour of ceramic such as tungsten carbide, silicon nitride, silicon carbide, etc. He found that tungsten carbide showed the best resistance whereas other compositions of industrial ceramic studied were found inferior to tungsten carbide.…”

Mining industries extensively use pumps for disposing water mixed with slurry. The pump impellers often get eroded while draining the mixture containing solid particles and water. The impeller shafts are commonly made of stainless steels. Though several types of other thermal sprayed coatings are well known, the attention has been focused on plasma and detonation sprayed coatings in the present investigation. An experimental investigation was made involving variations in parameters such as surface velocity, time of erosion and slurry composition using a pot erosion tester. It is observed that mass loss increases with increase in surface velocity and duration of exposure in such conditions. Increase in slurry composition reveals the initial increase in mass loss. However, this trend cannot be overestimated. Surface characterisation studies were made using XRD and SEM. The observations indicate that the SEM morphology for detonation spray coated material reflects better adhesion leading to negligible wear when compared with the plasma sprayed coatings.

“…The white regions represent Ni-Cr binder phase (denoted by C). Cr 3 C 2 grains have grown by liquid phase transportation through the Ni-Cr binder phase (solution-reprecipitation) and facetted grains grew more rapidly by grain boundary diffusion mechanism [28][29][30]. Ostwald ripening is also another densification mechanism in liquid phase sintering systems which also cause grain growth.…”
