Embodiment 1
[0033] Embodiment 1 metal material laser surface carburizing process
[0034] Colloid preparation. Choose toner with an average particle size of 10nm. In order to disperse the toner more evenly in alcohol and acetone, take such as figure 1 The method of compound adding of carbon powder and organic solvent shown. First, add 25g of carbon powder into the beaker, then add 50mL of alcohol and 10mL of acetone in turn, and stir with a glass rod when adding alcohol and acetone until the carbon powder has no obvious agglomeration. Then, after standing for 5 minutes, add 10g of carbon powder, then add 30mL of alcohol and 10mL of acetone in turn, and stir with a glass rod until a relatively uniform colloid is formed, and finally stand for 5 minutes to obtain a uniform "carbon powder-alcohol / acetone colloid "In the process of adding carbon powder and organic solvent twice, the purpose of the first time is to obtain a colloid with high viscosity, and the purpose of the second time is t...
