A system for causing wear to a material in representative downhole conditions is provided, and can include a housing with a chamber at least partially filled with a fluid, an abrasion device at least partially immersed in the fluid, a heat transfer element thermally coupled to a housing, an engagement arm coupled to the housing and a test sample attached to the engagement arm that can apply an engagement force to the test sample causing engagement of the test sample with the abrasion device. An actuation device can displace the abrasion device relative to the test sample, and cause wear of the test sample during a wear test in response to the engagement of the test sample with the abrasion device. A controller can control a thermal output of the heat transfer element to maintain the chamber within a temperature range that is representative of the downhole conditions.
