Embodiment 1
[0017] A corrosion-resistant tool for machining in a liquid, including a handle and a blade part, the handle part contains a bolt hole, and the bolt hole and the blade part have undergone corresponding surface treatment, so that cutting in a liquid with pH = 10 will not Corrosion occurs. The surface treatment of the bolt hole includes electrodepositing aluminum-oxidizing the aluminum layer: the anodizing process is: oxidizing solution component: Na 3 PO 4 12g / L, sodium pyrophosphate 5g / L, niacin 5g / L, 5g / L (NH4) 3 RhCl 6 ;The current density is 3A / dm 2 , time 100min, temperature 75°C; Al with a certain hardness is deposited on the blade part 93.5 V 2.5 Fe 2 PR 2 Amorphous protective coating, a process for micro-arc oxidation of an amorphous coating; the micro-arc oxidation process is: oxidizing solution component: Na 2 SiO 3 12g / L, sodium pyrophosphate 12g / L, sodium amino acid 1.5g / L, 1-5g / L (NH4) 3 RhCl 6 , the current density is 20A / dm 2 , time 9min, temperatur...
Embodiment 2
[0019] A corrosion-resistant tool for machining in a liquid, comprising a handle and a blade part, characterized in that the handle part contains a bolt hole, and the bolt hole and the blade part are respectively subjected to corresponding surface treatment, so that cutting can be performed in a liquid with pH=4 , no corrosion will occur. The surface treatment of the bolt hole includes electrodepositing aluminum-carrying out micro-arc oxidation to the aluminum layer, and the micro-arc oxidation process is: oxidizing solution component: Na 2 SiO 3 8g / L, sodium pyrophosphate 8g / L, 1g / L (NH4) 3 RhCl 6 , the current density is 15A / dm 2 , time 5min, temperature 40°C;
[0020] Al with a certain hardness is deposited on the blade part 89.5 V 2.5 Fe 2 Nd 6 Amorphous protective coating, said hardness range is Hv 300. Anodizing the amorphous coating, the anodizing process is: Oxidizing solution composition: Na 3 PO 4 8g / L, sodium pyrophosphate 1g / L, niacin 1g / L, 1g / L (NH4) ...
