Influence of the Processing Parameters on the Coating Hardness on LD10 A-Alloy
The paper discusses the influence of processing parameters on the hardness of LD10 aluminum alloy coating treated by the power source with positive and negative pulse in the alkaline electrolyte.Lots of experiments were done with different processing parameters including positive current density,negative current density,frequency,duty ratio,processing time and electrolyte temperature,and the micro-hardness tester HVS-1000 was used to measure the coating hardness.The results indicate that elevating the duty ratio,or reducing the frequency can be advantageous to improve the coating hardness,and the coating is the hardest treated in electrolyte at the 30℃.And when the value of the positive and negative current density is reasonable,and the processing time rationally matches with the current density,the coating with HV2800 can be obtained.
