Embodiment 1
[0017] Using industrial pure titanium (TA2) as raw material, anneal the industrial pure titanium block at 700°C, keep it warm for 2 hours, and use an electric spark cutting machine to cut the pure titanium metal block into sections with a size of 10mm×10mm and a length of 120mm. The blank, and the surface treatment of the blank, reaches the surface precision above grade 4, and the surface roughness of the blank should not be lower than Ra=1.25μm. Clean the surface of the blank with acetone, place the blank on a clean stainless steel tray, preheat it at a temperature of 60°C for 60 minutes, and then apply a glass lubricant on the surface of the blank by dip coating. The coating should be uniform. The thickness of the coating is about 0.2mm. After coating, the blank is dried at 60°C for 60 minutes. If there are defects such as falling coating, scratches, and peeling, it should be re-coated or washed off and re-coated. Use acetone to clean the surface and cavity of the mold with ...
Embodiment 2
[0020] Using industrial pure titanium (TA2) as the raw material, anneal the industrial pure titanium block at 750°C and keep it warm for 1 hour. Use an electric spark cutting machine to cut the pure titanium metal block into pieces with a cross-sectional size of 10mm×10mm and a length of 120mm. The blank, and the surface treatment of the blank, reaches the surface precision above grade 4, and the surface roughness of the blank should not be lower than Ra=1.25μm. Clean the surface of the blank with acetone, place the blank on a clean stainless steel tray, preheat it at a temperature of 80°C for 40 minutes, and then apply a glass lubricant on the surface of the blank by dipping. The coating should be uniform. The thickness of the coating is about 0.3mm. After coating, the blank is dried at a temperature of 80°C for 40 minutes. If there are defects such as falling coating, scratches, and peeling, it should be recoated or washed off and recoated. Use acetone to clean the surface a...
Embodiment 3
[0023]Commercially pure titanium (TA2) blocks are used as raw materials, and the commercially pure titanium blocks are annealed at 750° C. and kept for 1.5 hours. Use electric spark cutting machine to cut pure titanium block into blanks with cross-sectional size of 10mm×10mm and length of 120mm, and carry out surface treatment on the blanks to achieve a surface precision above grade 4, and the surface roughness of the blanks should not be lower than Ra = 1.25 μm. Clean the surface of the blank with acetone, place the blank on a clean stainless steel tray, preheat it at a temperature of 100°C for 20 minutes, and then apply a glass lubricant on the surface of the blank by dipping. The coating should be uniform. The thickness of the coating is about 0.4mm. After coating, the blank is dried at 100°C for 20 minutes. If there are defects such as falling coating, scratches, and peeling, it should be re-coated or washed off and re-coated. Use acetone to clean the surface and cavity o...
