Definitions
- the invention relates to a process for the manufacture of products, in particular decorative and others, with a coating applied to them.
- a method for manufacturing products e.g. Workpieces consisting of valve metals or their alloys and the subsequent application of a coating by means of micro-arc oxidation or electrophoresis in alkaline solution with the addition of additives (SU 9260084, 07.05.82).
- This method has the following disadvantages: 1. When machining the workpieces in the trough, the uneven distribution of the electromagnetic force field on the surface of a workpiece with a complicated shape has a negative effect on the quality of the coating. For this reason, the process of applying the coating to the hidden and shaded, i.e. poorly accessible parts of the workpieces very slowly or not at all. 2.
- the process control in the tub is associated with an unproductively large expenditure of electrical energy, especially in the case of machining local parts of the workpieces.
- the processing of workpieces with complex technology requires protection of the parts that are not subject to processing. It is also necessary to constantly mix the solution, which leads to a disorderly penetration of the particles into the burning zone of the micro arc.
- the invention has for its object to provide a method with which an increase in the quality of the products and an increase in productivity of the work can be achieved.
- This object is achieved by placing a nozzle element at a distance of 5-15 mm from the zone of the surface of the workpiece to be machined before the coating is applied. is brought, the nozzle cross section is selected depending on the nature of the part of the workpiece surface to be machined.
- By feeding the alkaline solution through the nozzle element it is possible to close the cathode-anode electrical circuit by means of the uninterrupted and positively targeted and / or self-draining solution jet to avoid additional cooling of the workpieces and to ensure that the coating melts through all its depth.
- the powdery components and / or the ultra-disperse powders necessary with regard to the chemical composition are used as additives.
- the nozzle element is moved continuously along the entire surface to be machined at a speed of not more than 25 mm / min with a temporary isolation of individual parts of the workpiece.
- Aluminum and titanium or their alloys such as e.g. Duraluminium 1, duraluminium hard, aluminum magnesium, AlMn (aluminum manganese) alloy rods based on titanium, A1V (aluminum vanadium) alloys based on titanium can be used.
- Disperse powder - AI, Ti and Mg can be used.
- a nozzle element When machining surface areas of workpieces with a rectangular shape, a nozzle element is preferably used, the nozzle cross section of which has a rectangular shape.
- the formation process of the coating is not intensified by means of a random (accidental) impact of the powder particles of the powder in the micro-arc. Burning zone, but by means of the targeted electricity.
- Micro-arc discharge causes a large increase in the current, by increasing the electron conductivity.
- Example 1 The workpiece is installed and started on an electromechanical lathe (not shown).
- the alkaline solution is automatically (or inevitably) directed onto the surface of the workpiece to be machined by the nozzle element.
- Voltage is applied between the workpiece and the nozzle.
- the end of the cathode-anode electrical circuit passes through the emerging beam of the solution.
- the solution can be given simultaneously through one or more nozzles, depending on the
- the solution can contain the ultra-disperse powders necessary with regard to the chemical composition.
- the constant concentration of the powder in the solution is maintained in that powder through the Powder dosing device can be added.
- Example 2 It is required to get a wear-resistant decorative coating on the right-angled part on a flat workpiece (plate) made of the alloy AlMg 2 .
- the insulating conductor (conductor) with the opening with respect to the rectangular part was manufactured.
- the nozzle element for the supply of the alkaline solution is placed at a distance of 10 mm from the surface to be machined and firmly anchored on the mechanism for the displacement of the nozzle element.
- the adjustment was made parallel to the processing surface with different speeds, which were given in table 2.
- the diameter of the outlet opening of the nozzle is significantly less than the width of the part to be machined. Therefore, the nozzle is moved in one pass along the length of the part, then across the width at a distance of 0.9 from the diameter of the nozzle, again offset across the length of the part.
- the example in question shows the possibility of obtaining the coating on a single one
- the method of manufacturing the products in this way increases the quality of the products and the labor productivity.
- the method according to the invention can of course also be applied to other materials, e.g. Metals or alloys in general, provided that a circuit can be closed between them and the nozzle. If necessary, this can be done by an electrically conductive coating of the workpiece.
- the invention can be used, for example, in the manufacture of products made from valve metals and their alloys. Table 1:
