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 …

Einfluss der Prozesskette auf die Feinkornbeständigkeit von mikrolegierten Einsatzstählen
Considering the processing of case hardening steel components, the machining as well as the heat treatment offer great capability for cost savings. By increasing the carburising temperature from today approximately 940°C up to e.g. 1050°C significant process time reductions are achievable due to …

Drying of cellulose nitrate plastic by means of conditioned air
… nitrate plastic. The conditions causing case-hardening and physical damage were observed, drying rate was determined and drying time compared. Specimens of cellulose nitrate plastic sheet, plasticized with camphor, were soaked in 95 percent ethyl alcohol. They were first dried in a …

A photoelastic study of stress distribution in a spur gear tooth
… a supporting evidence to the common practice of case-hardening the gear teeth. Previously this was done according to the mechanical properties of the gear materials, but without any analytical basis. Gear stress is a very complicated problem which includes in general the static, dynamic and …

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 …
