Corrosion resistance of PPTA Ni-based hardfacing layers
Materials ScienceIn this study, the corrosion resistance of four different hardfacing layers in a 3.5% NaCl solution was tested. Using 316L steel as a reference material, NiCrBSi, NiCrBSi + 35 wt% WC, and NiCrCuMo were deposited onto a structural steel S235JR substrate ...

Advanced chromium carbide-based hardfacings
Surface and Coatings Technology, 2012Abstract Ceramic metal composite powders are widely used in thermal spray technologies; however, application of such hardphases in cladding systems has not been strongly developed yet. In the present study, two different hardfacings produced by the plasma transferred arc (PTA) process were analysed and compared to reveal differences between NiCrBSi ...

Wear resistance and microstructural evaluation of a hardfacing welded S355J2 steel pipe piles
Materials Testing, 2022Steel pipe piles are used to reinforce the grounds. Due to high hardness of the rocky materials, in some cases, the tip surface should be developed with new designs in terms of geometry, material and heat treatment.

Abstract Hardfacing refers to the deposition of a specially selected material onto a component in order to reduce wear in service as a preventative measure or return a worn component to its original dimensions as a repair procedure. This article provides information on various hardfacing materials, namely, iron-base overlays, chromium ...

Hardfacing of Bulk Nanophase Coatings
Japanese Journal of Applied Physics, 2012This paper discusses the production of iron-based nanophase hardfaced coatings by means of common arc welding methods. The key is the exact, close-to-eutectic composition of the newly developed alloys. In combination with a precise control of the dilution of the base metal, this results in an eutectic composition of the coating, which allows the in ...

Alloy classification of hardfacing materials
International Journal of Pressure Vessels and Piping, 1991Abstract The detailed nature of abrasive and impactive wear are discussed briefly, after which the various processes used for the laying down of hardfacing materials on metallic surfaces are described. The advantages and disadvantages of the various processes are considered in detail. The primary section of this paper consists of a classification of

Hardfacing with Cobalt-Base Alloys
Indian Welding Journal, 1978Hardfacing alloys have assumed greater importance in the present day advancement in technological era. Modern technology has created operating and manufacturing conditions necessitating higher duty cycles on equipment and process. Maintenance and replacement are costly items-when converted to money in terms of downtime and production loss.

Electron Beam Glazing of Hardfacing Alloys
MRS Proceedings, 1983ABSTRACTElectron beam glazing has been used to reprocess hardfacing deposits of conventional Stellite 6 alloy, and TiC, TiB2 particle strengthened Stellite 6. By varying the scanning mode and power density, a wide variety of microstructures have been developed, with significant increases in hardness.
