Definitions
- the present invention relates to the process of weldplating workpieces of one metal with another metal.
- Such weld-platings are often needed to make certain surfaces, for example, the inner walls of boilers, resistant to corrosion or to wear.
- the chief fields of application are nuclear-reactor technology, processing technology in the chemical industry, and also the machine building industry.
- One object of the present invention is to avoid the cracking described above and, in general, to weldplated parts made of steel containing enough carbon to be hardenable, with metals of another type, such as austenitic stainless steel. in an improved manner.
- this object is attained by first surface decarbonizing the steel part, and then weld-plating the part.
- the effect is that a relatively low carbon steel surface is weld-plated.
- the weld-plating with austenitic stainless steel is facilitated.
- the cracking of the steel surface subjected to the weldplating heat is avoided.
- a pre-treatment which consists of decarbonizing the steel surface to be plated, to a depth of approximately 1 to 5 mm.
- this decarbonizing operation can be effected by a heat treatment of up to l,O00C. maximum, and preferably from 800 to 900C, in a decarbonizing gas atmosphere.
- Another possibility consists of coating the surface which is to be decarbonized with a l to 2 mm thick layer of a paste having a decarbonizing action, followed by a heat treatment in a protective-gas atmosphere at the aforesaid temperatures. with removal of the applied layer prior to the actual weld- 2 plating operation.
- Gases effective in this process are the so-called forming gases, e.g., mixtures of nitrogen and 20% hydrogen, or a mixture of hydrogen, carbon dioxide and carbon monoxide, or a hydrogen-argon mixture or other combinations having the same effect.
- the time needed for the decarbonizing depends on the carbon content of the steel, on the temperature used and on the hydrogen content or the decarbonizing power of the gas. The higher the temperature, the shorter the necessary heat treatment time.
- Parts of the surface of the material that are not to be plated or decarbonized may be covered with suitable protective pastes, as is known from case-hardening technology.
- the degree of decarbonization should be carried as far as possible.
- a carbon-steel with 0.6% of carbon should have a surface layer containing less than 0.15% carbon.
- a heating time of 5 hours is needed at a temperature of 900C.
- the depth of decarbonization depends on the so-called penetration by burning during the plating process. The less this is, the less can be the decarbonizing depth, and the shorter the pre-treatment time.
- Some parts to be weld-plated may be too large for the available decarbonizing furnace. Often these parts are fabricated from separate parts which are not individually too large. The separate parts may be processed as described hereinabove including the weld-plating, and the parts then welded together, the weld connections often being amenable to usual plating methods.
