The Influence of the Deposition Rate of Application on the Thickness of the Molybdenum Layer

Our research was based on the requirements of practice. The production organization asked us to solve the problem of application of molybdenum layer thermal spraying. In some samples, a large thickness was measured, making it impossible to produce the product of the required parameters. The product was a molybdenum lamella for brakes and clutches. The rate of application should be constant throughout the production of the lamella. Exceeded thickness is caused by the use of a large volume of additive material. Molybdenum is a very expensive metal, which ultimately results in a financial loss. In the paper we reviewed various causes of this problem and their onsequences. Based on the research, we determined that the main cause of the large thickness of the applied layer was the non-compliance with the constant molybdenum wire feed rate. We have taken corrective measures to prevent it from happening again. Linking with practice and handling manufacturers' problems is very important for our research.
