Abstract: A method of coating a vehicle wheel (10) to increase wear and corrosion resistance of the vehicle wheel (10), includes the steps of providing a vehicle wheel (10) and applying a wear and corrosion resistant coating (14) onto a surface of the vehicle wheel (10). The coating (14) is applied to at least a tire bead retaining flange (16, 24) of the vehicle wheel (10). The coating (14) is of particular use with vehicle wheels (10) made of forged aluminum. The coating (14) is selected from tungsten carbide, optionally including cobalt or chrome, a nickel-based superalloy, aluminum and silicon carbide, or stainless steel. The coating (14) is typically applied to a thickness of about 0.004 - 0.01 inch. The surface of the vehicle wheel (10) may be prepared by mechanically abrading the surface or chemically etching the surface of the vehicle wheel (10). The coating (14) may be applied by cold spraying, thermal spraying, or triboelectric discharge kinetic spraying and other similar processes.

Abstract: A grinding wheel comprising a cylindrical hub of a desired material having a first band of yieldable material on its outer circumferential surface, and a second band of abrasive material on the outer circumferential surface of the first band. The first band of yieldable material can be flexible or semi-flexible and provides support for the second band. An adhesive can be used to avoid relative motion between the hub and the first belt, and between the first and second belts.

Abstract: An ultrasonic inspection system is used to inspect grinding wheels used to prepare work rolls used in metal sheet production. The grinding wheel inspection system includes a test stand adapted to rotatably support a grinding wheel. An ultrasonic transmitting and receiving apparatus passes sound waves through the body of the grinding wheel. The attenuation of the sound waves passed through the grinding wheel is recorded in a recording device and analyzed in a computer. The recording device, which may be the computer, preferably records amplitude attenuation of the sound waves. The computer analyzes the amplitude attenuation, records the amplitude attenuation as an indicated density profile, and displays the indicated density profile on a computer screen for inspection. The indicated density profile of the inspected grinding wheel may be compared with indicated density profiles of other grinding wheels, particularly those with known operational characteristics.
