Embodiment Construction
[0015] The present invention will be further described below:
[0016] The mechanical part surface oxidation process of the present invention is characterized in that, comprises the following steps:
[0017] (6) Use sodium phosphate, glycerin, ethylenediaminetetraacetic acid, wear-resistant agent, sealing agent and titanium to form an electrolyte for standby;
[0018] (7) Fix the mechanical parts in the electrolytic cell with tooling;
[0019] (8) Adjust the distance between cathode and anode to 32~38mm;
[0020] (9) Using AC to evaluate the current density is 10A / dm 2 Reciprocate the cathode over the surface of the mechanical part;
[0021] (10) Rinse with deionized water for 5 minutes, and then polish and polish with 1000-mesh water abrasive paper to complete the process.
[0022] Specifically, silicon carbide and graphite powder are used to form the anti-wear agent. The sealing agent is composed of microcrystalline paraffin wax and alumina.
[0023] Further, the movem...

The invention discloses a mechanical part surface oxidizing process. An electrolyte is prepared from sodium phosphate, glycerin, edetic acid, a wear-resistant agent, a sealant and titanium for standbyapplication; a mechanical part is fixed in an electrolysis tank through a fixture; the distance between an anode and a cathode is adjusted to be 32-38 mm; the cathode is made to reciprocate above thesurface of the mechanical part by utilizing the alternating current density of 10 A / dm2; and deionized water is used for flushing the mechanical part for 5 min, and then 1000-mesh waterproof abrasivepaper is used for polishing and grinding the mechanical part, so that the process is completed. Compared with the prior art, the mechanical part surface oxidizing process is used for carrying out electric oxidizing on the surface of the mechanical part, so that the hardness and smoothness of the surface of the mechanical part are improved, the service life of the mechanical part is prolonged, andthe mechanical part surface oxidizing process has popularization and application value.
Description
technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a surface oxidation process of mechanical parts. Background technique [0002] Machinery refers to the general term for machines and mechanisms. Machinery is a tool device that can help people reduce the difficulty of work or save labor. Items such as chopsticks, brooms, and tweezers can all be called machines, and they are simple machines. A complex machine is composed of two or more simple machines. These more complex machines are usually called machines. From the point of view of structure and motion, there is no difference between a mechanism and a machine, and it is generally called a machine. In the prior art, most of the mechanical parts have relative motion in the mechanical structure, but the mechanical parts are not resistant to wear and corrosion, resulting in a reduced service life. Therefore, there is room for improvement. Contents of the invention...
