Abstract Improved product development, assessment methods and evaluation studies of materials for oil sands applications have traditionally focused on low and high stress abrasion and slurry erosion resistance because these wear mechanisms were considered to predominate in oil sands mining, transportation and bitumen recovery.
More recently with the successful introduction of oil sands hydraulic transportation systems, there has been increasing use of crusher and slurry handling systems in which materials of construction are also required to have good toughness and gouging abrasion properties, to withstand impact and the severe indentation and ploughing forces that are involved.
To assess material property requirements for mitigating these conditions, gouging abrasion testing using a modified ASTM G81 procedure, has been carried out on a range of materials of interest for oil sands processing service. The method involves a comparison of the wear losses that occur for reference and selected wear plates, when a controlled amount of standard feed rock is comminuted in a laboratory jaw crusher. Among the classes of material evaluated are abrasion resistant(AR) steel plates, austenitic manganese steel castings, chromium and chromium molybdenum white irons as plain castings and in laminated forms and also chromium carbide and tungsten carbide overlaid wear plates.
