Abstract
A machine, such as a hauler at a mining site, includes one or more bolted (clamped) joints. Friction coatings are applied to surfaces of two or more materials being clamped to reduce clamp load loss. The friction coatings include one or more coated surfaces and one or more interstitial spaces between the coated surfaces. Various materials may be used as the friction coating including, but not limited to, a tungsten/carbide or stellite/carbide alloy, iron base alloys such as POLYMET alloys, including PMET 290 (an alloy of iron, chromium, boron, manganese, silicone, and nickel), a nickel chromium alloy, e.g., Ni-20Cr, aluminum oxide (AlO) particles, and various combinations of these and other suitable materials.
