Tribocorrosion in PWR: A Parametric Approach

摘要

A specific tribometer equipped for electrochemical measurements in pressurized high temperature water (PHTW) is being used to study the effect of the water chemistry on the wear rate of a stainless steel. First results indicate that a slightly acidic pH increases drastically the wear rate compared to slightly alkaline pH. The influence of hydrogen partial pressure and contact kinematics is also described.
