INEL Spray-forming Research [PDF]

open access: yes, 1992
Spray forming is a near-net-shape fabrication technology in which a spray of finely atomized liquid droplets is deposited onto a suitably shaped substrate or mold to produce a coherent solid.

Influence of Cooling Rate in High-Temperature Area on Hardening of Deposited High-Cutting Chrome-Tungsten Metal [PDF]

open access: yes, 2015
The authors study the influence of cooling rate in high-temperature area for thermal cycle of high-cutting chrome-tungsten metal weld deposit on the processes of carbide phase merging and austenite grain growth for the purpose of providing high hardness ...

Plasma-transferred arc-welded composite hardfacings with ZrB2 and TiC reinforcements [PDF]

open access: yesProceedings of the Estonian Academy of Sciences
The traditional approach to prolonging the lifetime of wear parts is to use wear-resistant materials. One such material is hardfacing, which, in addition to its primary function, contributes to sustainability objectives by preventing the failure of wear ...

Wear behaviour of laser cladded Ni-based WC composite coating for Inconel hot extrusion : practical challenges and effectiveness [PDF]

open access: yes, 2016
In forging, tooling costs make up a significant percentage of the total manufacturing cost. To combat tool failure, forging dies can be manufactured using or including layers of high wear-resistant alloys.

Identification of internal defects of hardfacing coatings in regeneration of machine parts

open access: yesE3S Web of Conferences, 2017
The quality control of hardfacing is one of the areas where non-destructive testing is applied. To detect defects and inconsistencies in the industrial practice one uses the same methods as in the testing of welded joints.

Hardfacing alloys for excavator teeth coating

open access: yesZavarivanje i zavarene konstrukcije
The capacity of the rotor excavator depends to a significant extent on the backet teeth. Abrasive wear of cutting teeth and cutting edges is typical when digging sand, sandy clay and gravel in common rock environments. Of particular importance is the contribution of the correct geometry of the teeth, their position on the backet, and especially their ...

Effects of heat treatment on mechanical properties and microstructure of tungsten fi ber reinforced grey cast iron matrix composites [PDF]

open access: yes, 2009
In this study, grey cast iron matrix composites reinforced by different volume fractions of tungsten fibers (Vr = 0.95 %, 1.90 %, 2.85 %, 3.80 %) were investigated in as-cast and under the heat treatment temperatures of 1,000℃ and 1,100℃.
