Resumen

DE MELLO, José D.B  y  BALSAMO, Paulo S. de S. Tribologic Behavior of Stainless Steels for Cutlery. Inf. tecnol. [online]. 2006, vol.17, n.6, pp.57-62. ISSN 0718-0764.  http://dx.doi.org/10.4067/S0718-07642006000600010.

A study was made of the tribologic behavior of stainless steel used in cutlery. Abrasive and sliding wear tests were carried out on martensitic and ferritic stainless steels which had different contents of carbon and chromium. Although the chemical composition and heat treatment considerably modified the microstructure and hardness of the steels, these treatments had no significant effect on abrasion resistance and the friction coefficient. The sliding wear rate grows with the contact potential, suggesting that sliding wear in these steels is associated with the formation of protective oxide coatings

Palabras clave : tribology; cutlery; stainless steel; micro-abrasion; wear of materials.
