Abstract

fetched live from OpenAlex

Machinery used in mining and mineral processing industry suffers from severe degradation through abrasive wear. The current techniques used to extend the wear life of components exposed to these environments include the heat treatment of steels and the hardfacing of surfaces using fusion welding techniques. However, thermal spraying techniques such as the use of high velocity oxy-fuel (HVOF) composite coatings based on WC–Co system offer better wear resistance and greater flexibility in application. The ability to deposit microstructured coatings by the HVOF process is well established, but the ability to deposit nanostructured coatings is relatively new and posses a challenge. This paper reviews the application of the HVOF coating technique, and compares the wear resistant behaviour of a C–Mn steel substrate coated using micro- and nanostructured WC–Co based coatings.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
