Abstract

The invention discloses a tire gauge part. A composite material layer containing more than 60% (Wt%) of indium, more than 8% (Wt%) of iron and more than 70% (Wt%) of indium and iron is arranged on the surface of the tire gauge part, and a plurality of salient point microcrystals are arranged on the surface of the composite material layer. The height of each salient point microcrystal is larger than 100 nm and smaller than 500 microns, the top of each salient point microcrystal with the diameter larger than 100 nm and smaller than 500 microns is spherical or approximately spherical, the indium content exceeds 60% (Wt%), the iron content exceeds 8% (Wt%), the total indium and iron content exceeds 70% (Wt%), and the salient point microcrystals and the composite material layer are integrated. The part surface composite material layer and the base material are integrated. The material layer attached to each small hole is removed to form the tire gauge part.

Description

technical field [0001] The invention relates to a tire pressure gauge part. Background technique [0002] Surface acoustic wave is an elastic wave that propagates along the surface of a solid, and its energy is mainly concentrated in the range of one to two wavelengths below the surface of the solid. At the same frequency, the wavelength of the surface acoustic wave is only one hundred thousandth of the wavelength of the electromagnetic wave. Therefore, the surface acoustic wave device is more conducive to miniaturization design. SAW devices are elastic waves propagating on the surface of piezoelectric materials, which do not involve the migration of electrons inside the material. Therefore, SAW devices are less susceptible to electromagnetic interference. With its wireless and passive features, it can solve the shortcomings of existing direct tire pressure sensors that require batteries, and has its unique application trend in extremely harsh environments such as flammabl...
