DigiChrom: A Domain Ontology for Semantic Representation of Trivalent Chromium Platings and Its Large Language Model‐Based Alignment With Multiple Mid‐Level Ontologies

Advanced Engineering Materials, EarlyView.
Digitalizing electroplating requires both domain knowledge and interoperability. This work introduces PlatOn, a domain ontology for trivalent chromium plating and coating characterization, and a hybrid pipeline that aligns it to a mid‐level reference ontology by combining eight similarity metrics with language model reasoning. Expert‐validated mappings

Hardening behavior and property of wear of laser transformation hardened steel.

Journal of the Surface Finishing Society of Japan, 1989
Laser transformation hardening was carried out on two types of steel that differed in hardenability, using a 1kW CO2 laser under various conditions, and the effects of processing parameters-such as scan rate and the defocussing of the laser beam-on the hardened case depth and width, microstructure, hardness distribution and wear properties were ...
