Zeintzuk diren hari-txertaketen gainazaleko tratamenduak?

Thread insert surface treatment refers to the process of forming a covering layer on the surface of the workpiece through a certain method. After surface treatment, thread inserts can present a more beautiful appearance, and the corrosion resistance of the thread insert itself will also be improved. The more important purpose is to make the thread insert itself anti-corrosion, so as to increase the reliability and adaptability of the fastener. Electroplating, hot-dip galvanizing, and mechanical plating are the three most commonly used methods for surface treatment of thread inserts.

1. Electroplating
The electroplating of thread inserts refers to immersing the parts of the thread inserts that need to be plated into a specific aqueous solution. The aqueous solution will contain some deposited metal compounds. In this way, after the current passes through the aqueous solution, the metal substances in the solution precipitate and adhere to the thread inserts. on the immersed portion of the firmware. The electroplating of fasteners generally includes zinc plating, copper, nickel, chromium, copper-nickel alloy, etab. Sometimes boiling black (blue), phosphating, etab. are also included.

2. Hot dip galvanizing
Hot-dip galvanizing of fasteners is to immerse carbon steel thread inserts into a molten zinc plating bath with a temperature of about 510°C, so that the iron-zinc alloy on the surface of the fastener will be converted into passivated zinc. To obtain surface treatment effect (similar to hot dip aluminum plating)

3. Mechanical plating
Hari-txertaketen plakatze mekanikoak bitarteko fisiko eta kimiko espezifikoak erabiltzeari egiten dio erreferentzia hari-txertaketen gainazalean estalitako hauts metalikoarekin eragiteko., beraz, estalitako metalak estaldura bat osatzen du finkagailuaren gainazalean soldadura hotz bidez gainazalaren tratamendu efektua lortzeko. Finkagailuen plakatze mekanikoa ordezko piezetarako egokia da batez ere, hala nola torlojuak, fruitu lehorrak eta garbigailuak.

Hari-txertaketaren gainazaleko tratamenduaren kalitatea epaitzeko, batez ere hariaren txertaketaren korrosioaren aurkako gaitasuna eraginkortasunez handitzen den eta igoerak espero diren baldintzak betetzen dituen egiaztatzea da.. Ikuskapen metodoa produktuaren lan-ingurunea simulatzea da, proba-baldintzak ezarri, eta korrosio-probak egin. Bigarren urratsa itxura egiaztatzea da.
