Inner hole cladding test

1.The inner wall of the cylinder liner is laser clad, the thickness of the cladding layer is 0.3-0.6mm on one side, the surface of the cladding layer is continuous and uniform, and no pore defects are found.

  1. Cut the cladding layer along the vertical cladding scanning direction to prepare the metallographic sample. Use the 100x lens of the metallographic microscope to observe the bonding between the cladding layer and the substrate and the internal quality of the cladding layer. The cladding layer and the substrate are metallurgically bonded, the melting depth is shallow, and there is no unfused and pore defects inside the cladding layer. The thickness of the cladding layer is about 0.3mm.
  2. Grind the cladding parts, and keep the thickness of the cladding layer at about 0.15mm, with a surface roughness of Ra0.8. According to the GB/T10125-1997 standard, the neutral salt spray corrosion test is carried out. After 100h of continuous spraying, the surface rust of the cladding layer is observed, and no rust spots are found on the surface of the cladding layer.
  3. Use a portable hardness tester to test the hardness of the cladding layer after grinding. Take 6 points evenly along the circumference of the experimental tube. The hardness range of the cladding layer is about 50-53HRC.
