The Effect of Contact Materials on Contact Welding and Temperature Rise
The purpose of this study is to investigate the effect of different contact materials on contact welding (or sticking), contact temperature rise and contact resistance behavior. The tests were conducted at two different contact forces to simulate the contact behavior either at different levels of device life or two types of device designs with different contact forces. The test was done by a model relay testing device under 13.5 V dc lamp load with 130 A inrush and 25 A steady state. The contact resistance, contact temperature rise and contact welding force were measured at various testing conditions. The data indicated: (a) that both contact force and metal oxide content were key parameters to determine contact temperature rise, (b) that the metal oxide content and contact force played a major roles on the strength and distribution of contact welding force, (c) that the contact close time also affected contact temperature rise greatly and (d) that contact resistance under lamp load testing was stable and did not have significant difference for all tested materials at two contact forces.
