Effect of surface hardening conditions on susceptibility of fasteners to hydrogen embrittlement
… the relationship between core hardness, case hardness, and case depth on susceptibility to hydrogen embrittlement of case hardened steel fasteners. While case hardened fasteners have been studied previously, there are currently no processing guidelines supported by quantitative data for …

The identification and validation of case hardening for extending charcoal briquette extruder lifespan
… restricting the business's ability to scale up. Case hardening was identified as a potential solution to increase the wear resistance of the extruders by diffusing carbon into key components of the machine such as the screw. Several steps were taken at MIT D-Lab to validate the case hardening …

An Experimental Evaluation of Micro-pitting Performance of Two Bearing Steels
… performance of two typical bearing steels. Case hardened roller specimens made of alloy 9310 and through-hardened roller specimens made of alloy 485-2 are procured. Test matrices are defined according to the Latin Hypercube Space Filling Design of Experiment approach and executed to evaluate …

The effect of base stock and additive packages in an automotive oil on the friction and wear behaviour of overhead camshaft and finger follower systems
… low load, mixed lubrication conditions using the case-hardened steel cam and chilled white iron follower combinations. The remaining cam materials, carbonitrided and induction hardened grey flake iron did not fail under similar test conditions due to the presence of free graphite in the …

Electromagnetic methods for measuring material properties of cylindrical rods and array probes for rapid flaw inspection
<p>The case-hardening process modifies the near-surface permeability and conductivity of steel, as can be observed through changes in alternating current potential drop (ACPD) along a rod. In order to evaluate case depth of case hardened steel rods, analytical expressions are derived for the …
