Slurry Erosion Resistance of Martenistic Stainless Steel with Plasma Sprayed Al2O3-40%TiO2 Coatings

The slurry erosion behaviors of pseudoelastic TiNi alloy were studied using the liquid/solid impingement system and compared with SUS 630 and 2Cr12NiMo1W1V alloy. The influences of erosion time and angle on erosion resistance of three materials were surveyed. The experimental results show that TiNi alloy has the highest erosion resistance among the three materials and SUS 630 stainless steel is more resistant than 2Cr12NiMoW1V alloy. The KQL-300 indentation tester was used to simulate the impact of particle on material surface during erosion process. The results show that the deformation mode of indention can be pile-up or sink-in and there is a good correlation between erosion resistance of material and its indentation deformation mode. The sink-in deformation mode indicates the higher resistance to erosion, and the pile-up deformation mode implies the lower erosion resistance.

Wear Characterization

In the present work, effect of various heat treatments on slurry erosion behavior of 13Cr-4Ni martensitic stainless steel (MSS) at different impingement angles has been studied. The as-received cast bars of MSS were given various heat treatments. These heat treatments involved the austenitization of cast steel at temperatures of 950° C, 1000° C and 1050° C for different soaking durations of 2, 4 and 6 h at each temperature. This was followed by oil quenching then tempering for 1 h at a 600° C air cooled. Heat treated MSS samples were characterized for microstructure and mechanical properties viz. hardness, ductility (% elongation), tensile strength (UTS), and toughness. For wear characterization, slurry erosion tests were conducted at different impingement angles for as-received cast and heat treated samples. The heat treated MSS shows approximately 34% lesser weight loss as compared to as-received cast MSS. Increase in toughness of heat treated samples is found to be responsible for the improved slurry erosion resistance. Impingement angle close to 0° showed least wear loss.

Abstract Slurry-handling equipment and pipelines particularly used in coal processing and mining industries are continuously exposed to the Impact of liquid-borne solid particles, resulting in progressive damage and loss of material. Cost-effective solutions to slurry erosion in aqueous media have been mainly limited to austenitic stainless steels, although coatings have been proposed. This work was aimed at evaluating the slurry erosion resistance of arc-sprayed coatings and determining what improvement IS achieved after laser melting. Multiphase and Type 316 stainless steel arc-sprayed coatings were obtained by arc spraying in air solid and cored wires. The surface of arc-sprayed coatings was melted using a pulsed Nd-YAG laser producing 1.06 µm wavelength radiation. Arc-sprayed and laser-melted coatings were slurry erosion tested at impact angles of 25° and 90° in a laboratory slurry jet erosion device using quartz sand as erodent. The evaluation of wear damage was done with a laser profilometer. Scanning electron microscopy and X-ray diffraction analysis were used to evaluate the microstructural changes which occurred after laser surface melting. Multiphase arc-sprayed coatings were more slurry erosion resistant than Type 316 stainless steel coatings. Improvement in slurry erosion resistance, particularly at the impact angle of 90°, was achieved by laser melting multiphase arc-sprayed coatings. Although deep microstructural changes occurred within coatings upon laser melting, the removal of stringers between sprayed platelets by laser melting was found responsible for the increase in slurry erosion resistance of multiphase laser-melted coatings.
