Co-Ni-Cr-B-Si alloy and tungsten carbide. 50% tungsten carbides.
Eutalloy® 10611 (UltrAloy) is a micro-pulverised cobalt-nickel-chromium alloy with a high concentration of Diamax particles. It has been developed for protective coating of parts which must provide exceptionally high resistance to abrasion and erosion. Thanks to a special matrix composition Eutalloy® 10611 makes it possible to protectively coat steel, stainless steel and cast iron parts working in temperatures of up to 700°C, providing at the same time excellent corrosion resistance.
There are two essential components to this alloy, the matrix and the hard-phase Diamax particles, both micropulverised.
The Co-Ni-Cr matrix of Eutalloy® 10611 is dense with special tungsten carbide hard particles, providing extra wear resistance.
The matrix has a hardness of ~55 HRC. The polygonal-shaped, tungsten carbide Diamax particles have a hardness of approx. 1900 HV.
Excellent resistance to low/medium-pressure abrasion, fine-particle erosion, also against impact. The special matrix composition ensures wear resistance up to 700°C, providing at the same time excellent corrosion resistance.
Base metals: For stainless, cast and other steels, and cast iron.
Used with a Eutalloy® system torch, the Eutalloy® 10611 alloy ensures coatings of smooth and uniform quality. The result is far superior to those obtained with conventional processes, saving the user on finish machining and other labour costs.
