Abstract
The invention relates to the technical field of the fastener, and specifically to a high efficient corrosion-resistant bolt for an internal combustion locomotive and a special corrosion-resistant technology. The special running environments (such as oil, water, air, vibration and high temperature) of the locomotive cause the failure of the fastening bolt because of the corrosion, so the hidden danger is brought for the running of the locomotive. The high efficient corrosion-resistant bolt for the internal combustion locomotive comprises a bolt body; the bolt body is made of the austenitic stainless steel material, or the outer surface of the bolt body made of the common steel is coated with the fluorine polymer coating, and the thickness of the fluorine polymer coating is 20-40 um. The improved high efficient corrosion-resistant bolt for the internal combustion locomotive and the special corrosion-resistant technology are capable of selectively solving the problem that the complicated oil, water and air environments in the locomotive running cause the failure of the bolt because of the corrosion, prolonging the service life of the bolt, reducing the maintenance cost, and improving the reliability of the locomotive.
Description
Technical field
The present invention relates to technical field of fastening, especially a kind of internal combustion locomotive efficient corrosion resisting bolt and special anti-corrosion technology.
Background technique
Bolt is made up of head and screw rod (with externally threaded cylindrical body) two-part, and need and nut screw connection, be the most frequently used fastening piece, application area is wider.The special running environment (Oil, Water, Gas, vibration, high temperature etc.) of locomotive causes existing clamping bolt to lose efficacy because of corrosion, brings hidden danger to locomotive operation.For preventing bolt corrosion from usually adopting the processing modes such as zinc-plated, surface oxidising on Ordinary Steel bolt body, for the bolt being arranged on bad environments place, also having there is the phenomenon lost efficacy that is corroded in existing aseptic technic, can not meet the needs of particular surroundings.
Summary of the invention
In order to overcome the deficiency of existing antiseptic effect difference, the invention provides a kind of internal combustion locomotive efficient corrosion resisting bolt and special anti-corrosion technology.
The technical solution adopted for the present invention to solve the technical problems is: a kind of internal combustion locomotive efficient corrosion resisting bolt and special anti-corrosion technology, comprise bolt body, described bolt body material is austenitic stainless steel material, or at the bolt body outer surface fluoropolymer coating that common iron manufactures, fluoropolymer coating thickness is 20-40 μm.
A special anti-corrosion technology for internal combustion locomotive efficient corrosion resisting bolt, bolt body surface spraying fluoropolymer, coating is more than 24 hours curing time under ambient temperature 25 ° of C.
The invention has the beneficial effects as follows, efficiently solve because oil-water-gas environment complicated in locomotive operation causes bolt to be corroded the fault lost efficacy, extend the working life of bolt, decrease maintaining cost, improve the reliability of locomotive.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is structural representation of the present invention.
1. bolt body, 2. fluoropolymer coating in figure.
Embodiment
If Fig. 1 is structural representation of the present invention, a kind of internal combustion locomotive efficient corrosion resisting bolt and special anti-corrosion technology, comprise bolt body 1, described bolt body 1 material is austenitic stainless steel material, or at the bolt body 1 outer surface fluoropolymer coating 2 that common iron manufactures, fluoropolymer coating 2 thickness is 20-40 μm, and coating is more than 24 hours curing time under ambient temperature 25 ° of C.
Internal combustion locomotive efficient corrosion resisting bolt and special anti-corrosion technology are divided into two classes, one class adopts resistance to anti-corrosion material directly to make by Bolt sizes specification, when meeting the basic mechanical property of bolt, bolt body 1 material selection austenitic stainless steel material, because the Kohlenstoffgehalt in its material composition is generally lower than 0.03% or containing Ti, Ni, can significantly improve its intergranular corrosion resistance performance, these bolts are used for the bolt making that nominal diameter is not more than 24mm.Another kind of is reach antisepsis at the surface spraying anticorrosive coat of current conventional stud, not in the traditional plating of employing or heat treatment technology, aseptic technic selects fluoropolymer-coated technique, coating thickness controls at 20-40 μm, coating is more than 24 hours curing time under ambient temperature 25 ° of C, fluoropolymer is generally long-chain charcoal fluorine compounds, the bond energy of carbon-fluorine bond is larger, more stable, the end of carbochain is surrounded by fluorine atom, effectively prevent the exposure of carbon atom and carbochain, therefore fluorochemical shows remarkable chemical stability, weatherability, the specific performances such as corrosion resistance, bolt after process antiseptic property in salt spray test can reach 2000h, bolt after spraying is hardly by the chemical corrosion of any kind, corrosion protection power far exceedes traditional fastener surface process, as zinc-plated, cadmium plating, hot galvanizing, Dacroment etc.
Internal combustion locomotive efficient corrosion resisting bolt after improvement and special anti-corrosion technology effective solve because oil-water-gas environment complicated in locomotive operation causes bolt to be corroded the fault lost efficacy, extend the working life of bolt, decrease maintaining cost, improve the reliability of locomotive.
