Nickel Based Alloy

Service and downtimes of waste incineration plants generate high expenses for their operators. State of the art is to protect high corrosion exposed components by cladding them with a nickel based alloy. The welded overlay is 2-3 mm thick and very expensive. It needs to be repaired at each service interval. An alternative coating consists of a thermal sprayed multilayer of a nickel based bondcoat and a ceramic topcoat. Thickness and costs of this multilayer are assumed to be in the range of about 10% of the currently used coating. A solvothermal treatment chemically densifies the coating. This leads to a significantly lower porosity whilst improving cohesion and hardness properties. This innovative process leads to a self-healing layer caused by the high temperature waste gas exposition as the driving force.

Incoloy Alloy

Abstract Alloy 890 provides improved properties over those of Incoloy alloys 800HT and 803 via the addition of silicon and molybdenum to optimize the performance of the alloy. Alloy 890 is typically 43% Ni, 25% Cr, 1.85 Si, 1.5% Mo, and 0.45% Nb, with the balance being principally iron. The alloy offers a significant improvement in resistance to high-temperature corrosion. This datasheet provides information on composition, physical properties, and tensile properties as well as creep. It also includes information on high temperature performance as well as forming, heat treating, and joining. Filing Code: Ni-611. Producer or source: Special Metals Corporation.
