Abstract:
The invention relates to a substrate with a corrosion resistant coating comprising at least one nickel layer and at least one chromium layer as finish. Between these layers, at least one tin-nickel alloy layer is deposited for suppression of corrosion reactions determined by CASS and Russian mud tests. The invention relates also to a method for producing such substrates with corrosion resistant coating.

Abstract:
A wire (10) has a steel core (12), a nickel sub coating (14) and a zinc or zinc alloy top coating (16). The steel core (12) has a carbon content ranging from 0.15 per cent to 0.35 per cent. The nickel sub coating (14) and the zinc or zinc-alloy top coating (16) are preferably in a mechanically undeformed state. The use of the nickel sub coating allows to decrease the thickness of the top coating without decreasing the corrosion resistance. A possible application of the wire (10) is its use in mesh panels for fish farming.
Abstract:
An article is coated with a multi-layer decorative and protective coating having the appearance of stainless steel (Figure 3). The coating comprises one or more electroplated layers on the surface of said article and vapor deposited on the electroplated layers a color layer comprised of the reaction products of refractory metal or refractory metal alloy, nitrogen and oxygen wherein the total nitrogen and oxygen content is from about 4 to about 32 atomic percent with the nitrogen content being at least about 3 atomic percent.
Abstract:
A ReCr alloy coating for a diffusion barrier applied to a substrate, characterized in that it contains Re in an atomic percentage of not less than 50 % and less than 90 % and Cr and inevitable impurities, essentially Cr, in the balanced content. A layer having a desired alloy composition can be formed on the barrier coating by the surface coating method or through the diffusion of a component of the substrate, and when the barrier coating is subjected to a homogenization heat treatment and thereafter a cementation layer containing at least one element of Al, Si and Cr is laminated on the barrier coating, these elements does not substantially diffuse. Further, a stress relaxing layer comprising an alloy containing Re can be inserted between the substrate and the barrier coating. The ReCr alloy barrier coating allows the suppression of the deterioration of a substrate and a corrosion−resistant coating layer due to the reaction of the substrate and the coating layer, which has conventionally been a severe problem in the field of corrosion−resistant coatings such as a ceramic coating for heat shielding on a substrate made of e.g. a nickel base alloy, Al (or Cr or Si) pack cementation, thermal spraying and the like, and thus allows the increase of the life of a device.

Abstract:
Methods for cracking hydrocarbons in reactor systems having improved resistances to carburization and coking. The reactor system comprises a steel portion having provided thereon a Group VIB metal protective layer to isolate the steel portion from hydrocarbons, applied to a thickness effective for isolating the steel portion from the hydrocarbon environment. The protective layer is anchored to the steel substrate through an intermediate carbide-rich, bonding layer.
