Abstract
[Summary]
[Subject]
A zinc coating is to be formed on a part for a chain by using means not involving the likelihood of hydrogen brittleness, to ensure both corrosion resistance and mechanical strength required of the part for a chain.
[Solution]
On an iron base 22 of a part for a chain, e.g. outer plate 12, is formed a zinc coating 24 in a hydrogen-free atmosphere, and a baked film 26 for the prevention of white rust is formed on the zinc coating. The zinc coating 24 is formed, for example, by dipping in molten zinc, painting, spray coating, or mechanical plating. The baked film 26 for the prevention of white rust is formed by painting and baking with use of a coating material which contains 10∼40% by weight of aluminum powder and 3∼40% by weight of a silicone resin.
Description
- The present invention relates to parts for a driving chain or a conveyor chain which are used in a corrosive atmosphere such as, for example, an atmosphere containing salt water, acid, or alkali.
- Zinc coating and nickel coating are usually adopted as means for preventing the corrosion of chains and sprockets.
- However, if the corrosion preventing means using zinc coating is applied to a component of a chain, the component will undergo hydrogen brittleness because hydrogen, which is generated in picking or plating for the formation of a galvanized film, penetrates into the metal texture of the component, with the result that the mechanical strength of the component after hardening is markedly deteriorated. Also at the time of forming a chromate film on the galvanized film there arises the problem of hydrogen brittleness of the chain component which is attributable to the acid contained in the treating solution.
- Further, since the chromate film is in the form of a gelled hydrate, which is softer than metals, the film will be destroyed in an early stage if the part coated with the film is a component of a chain subjected to the action of a shear stress and a tensile stress repeatedly. Also when a pin is press-fitted into outer plates of a chain or when a bushing is press-fitted into inner plates of the chain, the chromate film is often destroyed. As a result, the galvanized film loses its corrosion preventing property due to white rust and eventually the component of the chain is corroded by red rust.
- If the corrosion preventing means using nickel plating is applied to a component of a chain, the problem of hydrogen brittleness will become less serious than in the use of zinc plating, but since nickel plating is inferior in point of corrosion preventing performance, the iron base of the chain component will be easily corroded by red rust through pin-holes of the nickel plated film.
- Thus, the above plated films cannot maintain the required mechanical strength of chain parts and pose the problem of markedly deteriorated service life.
- According to the present invention, in order to solve the above-mentioned problems, there is provided a corrosion-resistant part for a chain which is obtained by forming a zinc coating on an iron base of the part for a chain in a hydrogen-free atmosphere and then forming a baked film for the prevention of white rust on said zinc coating.
- The zinc coating is formed for preventing corrosion of the iron base. In the present invention, the zinc coating is formed in a hydrogen-free atmosphere to obviate the problem of hydrogen brittleness with respect to the iron base of a part for a chain and thereby ensure the mechanical strength required of the part for a chain. Further, a white rust preventing baked film is formed on the zinc coating to prevent the formation of zinc oxide on the surface of the part for a chain.
- To be more specific, the zinc coating is formed, for example, by dipping in molten zinc, painting, spray coating, or mechanical plating. By adopting any of these means it is possible to form the zinc coating in a hydrogen-free atmosphere without the generation of hydrogen.
- Preferably, the baked film for the prevention of white rust is formed by painting and baking with use of a coating material which contains aluminum powder and a silicone resin. For example, in the case where the zinc coating is formed on an iron base of an outer plate of a chain and is flawed at the time of press-fitting a pin into the outer plate, the aluminum, which is contained in the baked film and which exhibits a greater ionization tendency than zinc and iron, protects both zinc coating and iron base. Besides, the silicon resin also contained in the baked film imparts a strong toughness to the same film and is superior in both heat resistance and weathering resistance. Further, the silicon resin functions to reduce a press-fitting load in assembling zinc- coated parts into a chain, for example, by press-fitting, thereby preventing damage to the zinc coating.
- The present invention is applied, for example, to such chain constituent parts as shown in Fig. 1 and a sprocket on which the chain is to be entrained. The chain, indicated by the
reference numeral 10, hasouter plates 12,inner plates 14, apm 16 press-fitted into theouter plates 12, a bushing 18 press- fitted into theinner plates 14, and aroller 20 disposed in surrounding relation to thebushing 18. Theouter plate 12 and theinner plate 14 come into sliding contact with each other at a high surface pressure, and so do thepin 16 and thebushing 18, and the bushing and theroller 20. The chain components with the invention applied thereto can be kept corrosion-proof even under such a working condition. For example, as shown in Fig. 2,zinc coating 24 is formed on aniron base 22 of theouter plate 12 in a hydrogen-free atmosphere, and abaked film 26 for the prevention of white rust is formed thereon. - In the present invention, the zinc coating is formed, for example, by dipping in molten zinc, painting, spray coating, or mechanical plating. By forming the zinc coating with any of such means it is possible to obviate the problem of hydrogen brittleness of the so-coated chain component and prevent deterioration in mechanical strength thereof. The chain component treated according to the present invention is useful particularly in a working condition in which the chain component undergoes a shear stress and a tensile stress repeatedly.
- In the present invention, a baked film for the prevention of white rust is formed on the zinc coating. This baked film is formed by painting and baking with use of a coating material which contains 10∼40% by weight of aluminum powder and 3∼40% by weight of a silicone resin.
- Since the aluminum powder exhibits a greater ionization tendency than zinc and iron, it functions to protect the zinc coating and iron base even in the event the zinc coating is flawed. If the content of the aluminum powder is less than 10% by weight, the corrosion-proof effect of protecting the zinc coating by virtue of the ionization tendency of the aluminum powder will be deteriorated markedly. And if the content of the aluminum powder exceeds 40% by weight, the adhesiveness of the baked film to the zinc coating becomes extremely low.
- The silicone resin imparts a strong toughness to the white rust preventing baked film and is superior in both heat resistance and weathering resistance. Further, the silicone resin functions to diminish a press-fitting load in assembling zinc-coated parts into a chain, for example, by press-fitting, thereby preventing damage to the zinc coating. If the content of the silicone resin is less than 3% by weight, the flaw and crack preventing effect against external forces will be greatly deteriorated. And a silicone resin content exceeding 40% by weight will result in marked deterioration in adhesiveness of the baked film to the zinc coating.
- More preferably, the coating material for forming the white rust preventing baked film comprises 35 wt% of aluminum powder, 35 wt% of a silicone resin, 16 wt% of an alkyd resin, 7 wt% of an aromatic solvent, 5 wt% of an ester type solvent, and 2 wt% of an additive.
- By way of comparison, pins, bushings, rollers and plates, as chain components, were galvanized and coated with chromate film, then assembled into a chain. On the other hand, according to the present invention, a zinc coating and a baked film for the prevention of white rust were formed in this order on each of pins, bushings, rollers and plates as chain components, which were then assembled into a chain. Using both chains, a salt spray test defined by JIS 2371 was conducted to check the corrosion preventing effect for the chain components treated by the present invention.
- As to the comparative chain, white rust occurred at press-fitted portions in 48 hours, and red rust occurred throughout the whole of the chain in 120 hours. In contrast therewith, as to the chain fabricated using the chain components treated by the present invention, white rust was observed only slightly and red rust was not observed at all, even after the lapse of 500 hours.
- According to the present invention, as set forth above, a zinc coating is formed on a part for a chain in a hydrogen-free atmosphere, whereby it is possible to obtain a corrosion-proof zinc coating without hydrogen brittleness of the part for a chain. Thus, it is possible to obtain a chain superior in both mechanical strength and corrosion resistance. Moreover, since the baked film for the prevention of white rust is formed directly on the zinc coating, the formation of zinc oxide on the zinc coating is prevented and the problem of white rust peculiar to zinc coating is solved.
