Definitions
- the invention relates to a protective layer, in particular as corrosion protection on weapon parts, such as a machine gun, as well as parts of a carriage, a tower or the like receiving devices, in particular for a weapon that are exposed to different environmental pressures and influences.
- weapon parts of a weapon are subject not only to different mechanical requirements but also to different environmental influences.
- the problem of corrosion protection of weapon parts is currently not considered large. With the given short maintenance intervals of the weapon trying to solve this problem by cleaning and appropriate cleaning products. Accordingly, the cost of cleaning itself is very high.
- a corrosion-inhibiting color layer is often applied.
- the object of the invention is to provide at least the outer weapon parts of a weapon or parts of a carriage, a tower or similar receptacles for a weapon with an additional corrosion protection, especially when these parts are exposed to seawater or other environmental influences.
- the protective layer should not only be resistant to corrosion but also abrasion resistant.
- the invention is based on the idea of using a chromium layer as a corrosion layer. This is preferably applied galvanically. At points where these parts or their surfaces are subject to abrasion, a thin layer of silver is applied to the chromium layer. The silver layer acts like a lubricant. This has the unexpected effect of being able to dispense with other lubricants on the weapon parts. This effect therefore causes an increase in serviceability.
- the order of the silver layer is preferably carried out only in some areas that are exposed to abrasion. The same applies to the part that interacts with this part. Through the silver layer, both lubricate each other.
- chrome and silver layers can be applied to surfaces where the parts are intended for new construction as well as retrofits. Even used parts can be aftertreated with this method and re-installed in the same weapon.
- the abrasion behavior of the parts / surfaces is determined.
- the parts with a higher layer thickness could be subjected to a higher load than the parts with a smaller layer thickness.
- a layer thickness of more than 2 ⁇ m to 8 ⁇ m is to be provided.
- a layer thickness of 3-5 ⁇ m has been found to be sufficient.
- a pure chromium layer between 3-8 ⁇ m has been shown to be sufficient in the weapon parts such as closure housing, gas cylinder housing, etc. With an additional layer of silver, inter alia, the lock cylinder was provided.
- FIGURE shows a weapon part 1 (in this case a closure cylinder) with a chromium layer 2 on the surface 6 and an additional silver layer 3 on the chromium layer 2.
- the preferably additionally applied in the outer region 4 of the end face 5 silver layer 3 serves to prevent abrasion and causes self-lubrication in this area 4.
- the counterpart not shown here also has a silver layer in the corresponding area.
- the layer thickness of the chromium layer 2 can be chosen differently on the surface 6 of the respective component 1 to be treated and thus kept variable. The same applies to the layer thickness of the silver layer.
- EP 0352245 A2 for the application of the chromium as well as the silver layer in addition to the galvanic process and the flame spraying or PVD - method (Physical vapor deposition) according to EP 0352245 A2, EP 1 445 344 A1 or EP 1 400 293 A1 can be done in combination.
