Residual Stress Influence on Magnetic Properties of HVAF-Sprayed Metallic Materials for Load Cell Application
Magneto-elastic solid materials are commonly used as sensors in the development of load carrying body. As their magnetic properties change under mechanical loads, such material ability can then be used as internal or intrinsic sensor system, if integrated to the loaded part as a surface property, as applicable utilizing Thermal Spray Coating technologies. In magneto-elastic force sensors, applied stress modifies magnetic permeability of the sensing material, which can be detected with precision by PressductorŽ technology. Magnetic permeability of the given magneto-elastic material is a function of residual and applied stresses as well as texture and crystallite size. The working point of the sensor is therefore defined by texture, crystallite size and residual stresses in the magneto-elastic material.
