Titanium alloy Hydrogen embrittlement Auto wheels flange face flat nut.
Description
Titanium nuts generally refer to titanium hexagon nuts. Titanium nuts have high strength, high temperature resistance and corrosion resistance. They are used in conjunction with titanium screws. They are generally used on high-strength materials. The dimensions are the same as ordinary nuts.
During the production of fasteners throughout the year, in order to meet customer needs, a large number of titanium screws have been produced as inventory.
During the processing and treatment of fasteners, especially in the pickling and alkali washing before plating and subsequent electroplating, the surface absorbs hydrogen atoms, and the deposited metal coating then traps hydrogen. When the fastener is tightened, the hydrogen is transferred to the most concentrated part, causing the pressure to increase beyond the strength of the base metal and produce tiny surface cracks. Hydrogen is particularly active and quickly penetrates into the newly formed fissures. This pressure-break-infiltration cycle continues until the fastener breaks.
Usually Occurs within a few hours after the first stress application. In order to eliminate the threat of hydrogen embrittlement, fasteners should be heated and baked as quickly as possible after plating to make hydrogen seep out from the coating. Baking is usually carried out at 375-4000F (176-190°C) for 3-24 hours. Because mechanical galvanizing is non-electrolyte, this actually eliminates the threat of hydrogen embrittlement.
