Embodiment
[0034] Embodiment: Condition construction method for early warning monitoring of component surface failure in the present invention
[0035] Step 1 Prepare the driver layer:
[0036] Select 45# steel plate with a thickness of 4mm as the base material, and make it a standard sample with a length of 100mm, a width of 50mm, and a thickness of 3.5mm through shearing and grinding. The sample is subjected to a series of pretreatments such as degreasing and rust removal, surface activation, phosphating, cleaning, etc., and then a layer of epoxy resin is sprayed on the surface of the sample by electrostatic powder spraying technology as the driving layer, with a thickness of about 20 μm.
[0037] Step 2 Prepare the network bridge layer:
[0038] Cut the 30μm thick copper foil into the size of the sample, and use the method of integral pressing to make a "шшш" grid-shaped metal copper sheet, in which the fence and grid are both 1.5mm. Then two grid-shaped metal sheets are overlapped ...
