LECO Solutions for Steel

Precise measurement of carbon in carburized steel can be challenging due to changing concentrations throughout the hardened case of a sample. Glow discharge spectroscopy (GDS) offers a repeatable ability to measure carbon in a region spatially discrete from organic carbon on the near surface and in the base material. The presentation includes comparisons to other measurements, relationships to microhardness measurements, and characterization of the materials with GDS compositional depth profiles and bulk analyses.

Many steel components can benefit from surface hardening, which improves wear resistance while maintaining a part’s toughness. Surface hardening can be accomplished by nitriding, induction hardening, or even shot peening; but carburizing remains the most viable choice for many applications. In this webinar, Dave Coulston explains what carburizing is, how it is accomplished, and then describes the important chemical, metallurgical and mechanical property results of a carburizing treatment. This is followed by metallographic preparation of carburized steel and microscopic evaluation of the carburized layer.
