This document specifies methods and formulae for evaluating the risk of scuffing, based on Blok’s contact temperature concept.<\/p>\n

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 P\u00e9clet numbers.<\/p>\n
