Armour welding and bodywork
Milrem LCM has long-standing experience with heavy equipment bodyworks. In collaboration with our partners, we offer body painting services for equipment including large vehicles and equipment.
Milrem LCM holds an EN-ISO 3834-2:2005 welding certificate.
We also offer all interior repair and upholstery services, from seat restoration to the replacement of the entire vehicle interior.
Black oxide or blackening is a conversion coating for steel that provides metals with a matte black appearance. To achieve maximal corrosion resistance, the black oxide must be impregnated with oil or wax. Blackening has no significant dimensional impact. Besides steel, blackening can be used on other ferrous materials, such as stainless steel, copper, brass and copper-based alloys.
Application: commonly used on firearms, black oxide is also often used by the engineering and automotive industries.
Manganese phosphating, or Parkerising, is a method of protecting a steel surface from corrosion and increasing its resistance to wear through the application of phosphoric acid and manganese oxide. Parkerising produces a black or dark grey highly durable and corrosion resistant matte finish. The hard layer is usually very shallow, from 0.005 to 0.0075 mm. Similarly to black oxide, the Parkerised surface must be covered with a light coating of oil or wax to maximize corrosion resistance.
Application: ideal coating for gears, hand and air tools and firearms. Excellent for use under paint.
Nitriding is a heat treatment process that diffuses nitrogen into the surface of a metal to create a casehardened surface. Nitriding increases resistance to wear and corrosion.
Application: gasket sealers, heavy-duty components, bushes, camshafts, gears.
Ferritic nitrocarburising is a steel surface-hardening process that involves diffusion of both nitrogen and carbon into the part. The process produces a very hard surface that has exceptional resistance to wear. Ferritic nitrocarburising also increases fatigue strength and resistance to corrosion. Ferritic nitrocarburising is suitable for surface treatment of complex shapes because of the lack of dimensional changes and distortion. Ferritic nitrocarburising can replace blackening and black oxidizing of weapons, delivering a significantly more durable result.
Application: weapon components to achieve black semi-matte finish. Coating can be applied to all metal components of a weapon. Common applications in engineering include gears, shafts, dies, camshafts, and hydraulic piston rods.
