Scope

This document specifies methods and formulae for evaluating the risk of scuffing, based on Blok's contact temperature concept.
The fundamental concept is applicable to all machine elements with moving contact zones. The flash temperature formulae are valid for a band-shaped or approximately band-shaped Hertzian contact zone and working conditions characterized by sufficiently high Péclet numbers.
