Wear by slurry abrasion occurs during transport of abrasive slurries encountered in industrial and specially mining applications, extruders, and in slurry pumps. Steel piping systems are widely used in mining to convey the mineral, ore and tailing slurries to the processing plant, as well as to recycle the debris medium back to the mining area. Hardfacing by welding is one of the economic methods to improve wear resistance of engineering components. The present work reports slurry abrasion behaviour of hardfaced martensitic stainless steel under a wide range of experimental condition. The slurry abrasion experiments were performed using slurry abrasion test apparatus using silica sand as the abrasive medium. The effect of test parameter such as sliding distance, normal load and slurry concentration of abrasive medium on slurry abrasion behaviors of martensitic stainless steel was investigated. The slurry abrasion volume loss exhibited increasing trend with increasing sliding distance, normal load and slurry concentration, although the magnitude of increase was different in each case. The results of the investigation suggest and slurry concentration had relatively stronger effect as compared to that of normal load.. The morphological studies of the worn surfaces revealed characteristic differences in the wear pattern under different test conditions.

Wear by slurry abrasion is very expansive problem that must be taken into consideration while selecting the material for the transportation of slurry through pipeline. Abrasive wear generally occurs when abrasive slurries come in contact with the industrial engineering components or slurry transporting pipes. The abrasive particles carried by slurries eventually remove the material from the encountering surfaces which results in the early failure of the component in service. In present investigation an attempt is made to study the effect of load, slurry concentration, sliding distance on the abrasive wear behaviour of mild steel. The slurry abrasion experiments were carried out using slurry abrasion test apparatus with silica sand slurry. The findings of the present investigation indicate that slurry abrasion volume increased with slurry concentration, load and sliding distance, although the magnitude of increase was different in each case. The SEM observation of worn out surfaces revealed micro ploughing and micro cutting as wear mechanisms.

The engineering components are subjected to surface damage by slurry abrasion such as transportation pipes carrying ore and mineral slurries, extruders, sand pumps and agitators, Apart from stress, abrasive particle hardness, slurry concentration, particle size and shape significantly influences slurry abrasion rate. The effect of abrasive particle shape on slurry abrasion behaviour of steels and cast irons which are widely used for wear protection has not been studied. The particle shape assumes significant importance due to fracture and fragmentation of the particles during the process of abrasion. In the present work, the particle shape characterization of silica sand abrasive particles was carried by shape factor analysis using image analysis technique. An attempt was made to correlate the different measures of shape factor with particle size of abrasive particles over a wide range. The characterization of slurry abrasion tester was carried out using slurry abrasion tester with silica sand slurry. The effect of sliding distance on slurry abrasion volume of mild steel was studied. The volume loss increased linearly with sliding distance. The scanning electron microscopic observations of worn our surfaces showed micro-ploughing and cutting as mechanism of material removal.

Committee E-04 on Metallography of the American Society for Testing and Materials (ASTM) conducted an interlaboratory round robin test program on quantitative energy dispersive spectroscopy (EDS). The test program was designed to produce data on which to base a precision and bias statement for quantitative analysis by EDS. Nine laboratories were sent specimens of two well characterized materials, a type 308 stainless steel, and a complex mechanical alloy from Inco Alloys International, Inconel® MA 6000. The stainless steel was chosen as an example of a straightforward analysis with no special problems. The mechanical alloy was selected because elements were present in a wide range of concentrations; K, L, and M lines were involved; and Ta was severely overlapped with W. The test aimed to establish limits of precision that could be routinely achieved by capable laboratories operating under real world conditions. The participants were first allowed to use their own best procedures, but later were instructed to repeat the analysis using specified conditions: 20 kV accelerating voltage, 200s live time, ∼25% dead time and ∼40° takeoff angle. They were also asked to run a standardless analysis.
