“…Bhandari et al [100] conducted tests on WC-10Co-4Cr cermet coating deposited on CF8M steel (17-21 % Cr) by means of detonation gun-spraying. Slurry tests decrease surface roughness (Ra parameter) of both coating and bare steel, but the degree of this decrease was different for cermet coating and steel, and depended on the test conditions.…”

The degradation of materials due to slurry erosion is the serious problem which occurs in the power industries. The paper presents actual knowledge about an influence of individual factors connected with flow conditions, particles and material properties on the slurry erosion resistance. Among the factors connected with operating conditions, an influence of impact angle, and velocity of impact, particle concertation and liquid temperature have been described. In case of the factors connected with solid particle properties, an influence of the size, shape and hardness have been discussed. In the part devoted to the impact of material properties, due to different types of materials, the issues of resistance to erosion of slurries related to the properties of steel, ceramics and polymers are discussed separately. In the paper has been shown that a change of any of mentioned factors causes a change in the erosion rate due to the synergistic effects that accompany to slurry degradation.

“…Thus, two material removal mechanisms occurred in these specimens simultaneously, i.e., plowing abrasion and indentation, including mainly a ductile type of material removal. Bhandari et al [40] also observed similar characteristics during solid particle erosion of ferrous materials. The erosion traces of the plasma-nitrided specimen were shallower and more superficial than that of asreceived and tempered ones (figure 11c).…”

In this study, CrN and TiAlN thin films were deposited on plasma-nitrided QRO 90 Supreme hot work tool steel by physical vapor deposition process and analysed with regard to their erosion performance under hydro-abrasive erosion conditions. The as-received specimens were quenched to room temperature from 1050°C and tempered gradually at 605°C for 2 h and at 560°C for 4 h. These specimens were plasma-nitrided for 10 h at 500°C at a pressure of 250 Pa in a gas mixture of 80% N 2 ? 20% H 2 and then coated with TiAlN or CrN coatings by cathode arc evaporation. The specimens were characterized by metallographic techniques, SEM, EDS and micro-hardness test. Plasma nitriding and duplex surface treatments significantly increased the hardness of the specimens and thus significantly reduced the erosion of the specimens. The hardnesses on the surface of plasma-nitrided, CrN-deposited and TiAlN-deposited QRO 90 steels were 1092 HV 0.025 , 2436 HV 0.025 and 3578 HV 0.025 , respectively. TiAlN-coated specimens were about 17-fold harder than the as-received specimens and over 3-fold harder than the plasma-nitrided specimens. The erosion resistance of CrN-coated specimens was increased by a factor of 3.6 and 1.5 compared with that of the as-received and plasma-nitrided specimens, respectively. A brittle fracture phenomenon was observed on the eroded surface of the duplex-treated specimens while a ductile material removal was observed on the as-received and the tempered specimens. The plasma-nitrided specimens showed a mixed behaviour of ductility and brittleness. adhana(0123456789().,-volV)FT3 ](0123456789().,-volV)

“…Also, we can say that the slurry is mixture of solid eroding particles and liquid medium. 14,21,24,26,29,61,62 Similarly, centrifugal/submersible pumps employed for water supply from the rivers, reservoirs etc. through pipelines in domestic urban, industrial and rural areas with the purpose of sprinkling cum spraying for irrigation and other regular objectives have to undergo through erosive wear due to suspension of sand as erodent particles in flow.…”

Slurry erosion usually results in the form of damage to the materials of different components having underwater working domain. Numerous industries have suffered due to this kind of wear resulting in frequent breakdowns demanding repeated financial assistance and poor productivity. Properties and tribo-performance of materials related to distinct slurry applications play a significant role in arresting the slurry erosion wear. Slurry erosion depends on different parameters such as impact velocity, impingement angle, shape and size of erodent, slurry concentration and so on. These parameters differ from one application to another and accordingly, specific materials are selected knowing the extent and severity of slurry erosion wear. In the last decade, many authors studied parametrically the tribo-slurry erosion performance of materials, few of them correlated their investigations to the actual in situ conditions of applications. Various authors have analyzed the effect of operating parameters on the mechanism of erosion and conducted the comparative studies of different materials. Many of the investigators attempted to improve the properties and tribo-slurry erosion performance of materials through surface modification techniques; coating, reinforcement, heat treatment, thermo-mechanical process etc. This review is an effort to covers all such kind of explorations.
