Abstract
The article presents the proposal of using abrasive treatment in vibrating containers for surface treatment applied with the Electro Spark Deposition technique. In tests on a carbon steel the layer was applied with a tungsten electrode. After the tungsten layers were applied, a vibro-abrasive treatment was carried out. Changes in the geometrical structure of the surface of the deposited layers before and after vibratory processing were investigated. In addition, the chemical composition and the thickness of the coatings were examined.
Highlights
The article presents the proposal of using abrasive treatment in vibrating containers for surface treatment applied with the Electro Spark Deposition technique
The cost of regeneration of machine parts after wear or failures varies from a few percent of the value of the part being repaired
On the basis of 3D measurements of the geometric structure of the tungsten layers applied, it can be concluded that the smallest capacitance of the capacitors used has surfaces characterized by higher values of the highest elevation parameter of profile Rp, with a higher number of peaks with significant heights than those obtained with the largest capacitors capacity
Summary
The article presents the proposal of using abrasive treatment in vibrating containers for surface treatment applied with the Electro Spark Deposition technique. After the tungsten layers were applied, a vibro-abrasive treatment was carried out. Methods of regeneration and surface modification are many, depending on the expected properties of the coatings and conditions of use as well as the coating materials used [2, 3, 7]. The method of electro-discharge coating is associated with the transport of energy and mass under conditions of electric discharge between the working electrode and the workpiece. On the basis of 3D measurements of the geometric structure of the tungsten layers applied, it can be concluded that the smallest capacitance of the capacitors used has surfaces characterized by higher values of the highest elevation parameter of profile Rp, with a higher number of peaks with significant heights than those obtained with the largest capacitors capacity. Exemplary geometric structures of the surface are shown in fig. 2 and fig. 3
