This week we’ll be highlighting and sharing another powdered metal-related article written by TAT Technologies’ president, Harb Nayar. Titled Hardfacing and Welding Rods by PM (Published 1977, MPIF, reference 1077-0074), this article covers the process of producing hardfacing, welding, or brazing rods of pre-alloyed powders by a unique powder metal sintering process without a pressing step rather than the casting process dominant at the time of the article’s writing. By reading this article, you will learn about:
The direct particle liquid phase sintering process of relatively hard powder particles without any prior compaction.
How the final densities are above 95% of theoretical.
How this process can produce preforms, thin plates and rods from 1/16" to 1" equivalent diameter.
How this is very suitable for many Ni-base and Fe-base alloys with reasonably wide liquidus to solidus temperature ranges.
Overall, this article captures the flexibility of powdered metal process, and the spirit of innovation that makes it such a dynamic player in industrial manufacturing - everything TAT Technologies is trying to encourage today!
