“…Scratching of the wear surface is encouraged by a) hard wear surface so that it is not indented but gets only scratched by hard particles, b) high relative speed of solid particles with respect to target surface so that abrasives brush past the target surface and c) high concentration of solid particles (1,15) .

“…INTRODUCTION EAR of the materials exposed to a high velocity stream of slurry is known as slurry erosion. Slurry pot tester is one of the many important methods used to evaluate slurry erosive wear behaviour of materials [1]- [4]. Surface modification and use of hard coatings for preventing the failure of components in oil industry and hydro electric power plants is continuously increasing.…”

Abstract-This paper describes the erosive wear behaviour of Ni-WC coating deposited on mild steel by flame spraying process. A slurry pot tester with a provision for holding flat plate specimen (12X12X35 mm 3 ) was used to evaluate the erosive wear behaviour of the coating and mild steel. The wear test was conducted using two slurry concentrations (20% & 40% silica sand and water mixture) at three rotational speeds i.e. 600, 800 and 1000rpm. It was observed that the rotational speed affects the wear behaviour of coating and mild steel at both slurry concentrations. The increase in rotational speed showed continuous increase in the wear rate of the coatings for both 20 % and 40% sand slurry. The wear behaviour of coating has been explained in light of microstructure and microhardness. SEM study of wear surface showed that the wear of coating takes place by fragmentation, crater formation and abrasion.

“…When considering the properties individually, it has been found that the hardness played a main role in controlling the abrasive wear [13]. The compression strength could have a stronger influence on the abrasive wear property than the tensile strength thereby the load is applied in the form of compression thereby pressing the specimen towards the sand particles at the interface [14]. This attracted the attention to explore the possibility of a correlation between the selected mechanical properties and the wear loss of the hardfaced alloys.…”

“…The presence of a harder and less corroding phase in the target (sample) material leads to better wear response [18][19][20][21][22][23][24]. Experimental parameters include the nature of the electrolyte; volume fraction, shape, size and nature of the solid mass suspended in the electrolyte; and traversal speed and distance [4,[18][19][20][21][22][23][24][25][26][27][28][29][30]. Presence of hard suspended particles in the test environment and increasing traversal speed cause inferior wear behavior [4,[18][19][20][21][22][23][24][25][26][27][28][29][30].…”

This investigation pertains to the analysis of slurry wear behavior of a zinc-based alloy. The effects of material composition/ microstructure, slurry composition and traversal distance and speed on the response of the alloy system have been studied. Sample rotation method was adopted for testing the samples. In some cases, unexpected wear response (from conventional understanding) was observed. For example, presence of a less corroding phase like Si particles in the alloy system caused inferior wear response while increasing traversal speed led to improved wear behavior (in the liquid-only medium). Further, hard sand particles suspended in the test environment offered superior wear characteristics despite their additional erosive and abrasive damage to the samples. In the tested range (20-60 wt%) of sand concentrations in the slurry medium, the wear rate increased initially with increasing sand concentration, attained the maximum (although less than the liquid-only medium) at 40% sand and then finally followed a reversal in the trend at a still higher sand concentration of 60%. Increasing traversal speed from 4.71 to 7.02 m/s led to inferior response while the silicon containing alloy performed better than the one without the element in general in liquid plus sand slurries. The wear rate increased with traversal distance initially, attained the maximum and then decreased once again at still larger distances. The sensitivity of the rate of increase/decrease in wear rate with distance became less in the presence of suspended sand particles in the medium (electrolyte). The observed wear response of the samples has been substantiated through specific characteristics of affected surfaces. The latter also helped to understand the operating material removal mechanisms.
