摘 要：This investigation was prompted by results of a qualification test of a mechanism to be used for the James Webb Space Telescope.The wear phenomena were investigated using dedicated laboratory experiments. Tests were done using a vacuum roller rig for a range of roller misalignment angles. The wear in these tests was mainly adhesive wear. The measured wear rates were highly correlated to the misalignment angle.
