Abrasion Tester to simulate microscu00d3pico microscu00d3picos level events that give rise to wear by abrasion

摘要

A device for abrasion test, that puts in evidence or simulates Macroscopic, microscopic events that give rise to Abrasive Wear.In Practice (e.g.,Mining) abrasion is produced by the action of hard particles are forced against a metal surface (Low hardness) and slide against her leaving a Furrow and removing mateRial (wear).The Interaction between the abrasive and the worn Surface occurs under different micromechanisms that depend on the Geometry of the abrasive, angle of attack, penetration depthCoefficient of friction against the surface and properties of Abrasive material.The micromechanisms may act independently or in combination, and they are: micro furrowed, micro fatigue, micro Cutting and micro - wedge.As microscopic events are only visible in real time through an Electron Microscope.
