Slurry erosion characteristics of TiN coatings on α-Ti and plasma-nitrided Ti alloy substrates

Erosion wear behavior of laser clad surfaces of low carbon austenitic steel

“…Different methods like heat-treatment, surface coatings, etc. were employed to improve the surface characteristics of the target material to minimize the [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16]. Among these methods, the laser cladding process has many advantages over conventional ones such as good bonding between clad layer and substrate, low heat input and distortion of the substrate, etc.…”

“…They found that the ceramic coatings are effective in preventing the erosion damage to the pump impeller. Tu et al [7] fabricated TiN coatings on commercial ␣-Ti alloy and tested in jet-in-slit tester with angular silica sand at velocities between 6.4 and 15.2 m/s. They observed that the wear specimens show high slurry erosion resistance particularly at low velocities.…”

Wear and Corrosion Behavior in Different Materials

“…analyzed Ti/TiN multilayers with a soft compositional transition, which they produced with computer-controlled gas flow. The results revealed that both the interfaces, as well as the period modulation of the multilayers play an important role in improving mechanical properties [14,15]. This work compares the structure, morphology, grain size, fracture resistance, wear resistance, and corrosion resistance of multilayers as opposed to monolayers.…”

Al2O3 + TiO2 Thin Film made by Electrostatic Spray Deposition

“…Resistance of materials against slurry erosion depends on material properties (hardness, stiffness, toughness), flow rate, kinetic energy of impacting solid particles, angle of impacts, property of solid particles, e.g. shape and hardness, and in case of coated materials, erosion rate depends on coating stiffness, hardness, thickness and adhesion to a substrate, and also on the mismatch between substrate and coating properties [4][5][6][7][8][9]. Depending on material stiffness the maximum erosion rate of material is reached at different impingement angle.…”
