“…A similar result was noted by Santa et al [49], who related increasing size of impact craters to increased impinging particle size. The production of craters on the surface leads to the presence of crater lips that are subsequently removed by the cutting motion of the particles as the move out from the centre of the directly impinged zone.…”

A Ab bs st tr ra ac ct tThe present study examines three High Velocity Oxy Fuel deposited coatings, Tungsten Carbide, Chromium Carbide and Aluminium Oxide, under slurry erosion-corrosion conditions. Coatings produced in this manner typically exhibit superior density and hardness over alternative thermal spray technologies, therefore are suitable for use in corrosive and highly erosive environments. The scope of the study concentrates on isolation of the contributing factors of erosion, corrosion and synergy through applied electrochemistry, as well as metallographic analysis to evaluate the mechanisms causing coating degradation. Carbide with a Cobalt binder to be an effective protective coating, resulting in a significant reduction in total material loss over uncoated S355 steel.

“…Several deposition methods are used: e.g. the detonation-gun spray process [17], oxy fuel powder (OFP) process [18,19], wire arc spraying (WAS) process [18], high velocity oxy fuel (HVOF) process [19], physical vapour deposition (PVD) [20], plasma and flame spray methods (thermal sprayed coatings) [21], laser surface alloying (LSA) [15]. There are also other methods, which enhancement of slurry wear resitance, e.g.…”

Degradation of material caused by impacts of a solid particle (erodent) suspended in a liquid is called slurry erosion and is a major problem in the hydropower and maritime industry. Slurry erosion depends on many factors, e.g. liquid and erodent velocity, size, shape, angle of impact, hardness and number of erodents, and strength of a target material. The various types of test devices have been designed to investigate an effect of mentioned parameters on material resistance. In the paper are described main types of the test apparatus showing their main advantages and disadvantages. Some results of slurry erosion resistance of few groups of materials are also presented.
