销盘磨损试验

Pin on disk testing provides a method of characterizing the wear between two materials. Our 从事专家 use this method to evaluate the performance of a “wear couple” or to characterize the performance of different materials against a standard surface. 

Pin on disk can simulate multiple wear modes, 包括:单向, 双向, omnidirectional and quasi-rotational wear. Our equipment allows us to test virtually any combination of materials to determine the effect of wear on a medical device. While we can accommodate a variety of projects, we commonly test in reference to ASTM G99, ASTM G133和ASTM F732.

什么时候需要进行磨损试验?

 The FDA and other regulatory bodies will often request mechanical wear testing when the device being tested is introducing a new material couple, or if a new material interaction hasn’t been adequately characterized through mechanical testing alone. 

Wear testing is also critical for comparing the wear properties of new devices to a previous generation device. 然而, 这可能不符合成本效益, 或者是可行的, to perform wear testing on a finished product. Pin on disk testing allows for quick simultaneous comparison of multiple materials under controlled conditions.

After completing pin on disk testing, our 从事专家 conduct mass-loss evaluations and particulate analyses of test fluids to characterize wear debris. 除了, profilometry can be utilized to evaluate the changes in surface topography due to articulation. 冶金评价 of the post-test wear scarring can also be performed. 在某些情况下, we can also introduce third body debris to characterize wear under real-world worst-case conditions. 

High capacity pin on disk testing

im体育APP performs 销盘磨损试验 in reference to ASTM G99, ASTM G133和ASTM F732 on our in-house, 定制的, 12工位磨损试验架. 这些独特的, high capacity machines allow for the testing of several material combinations at a time, 在单个测试框架上. The 12-station setup also allows for additional confidence by testing multiple samples per condition.
