Abrasive Wear Resistance of the Iron- and WC-based Hardfaced Coatings Evaluated with Scratch Test Method
Journal Title: Tribology in Industry - Year 2013, Vol 35, Issue 2
Abstract
Abrasive wear is one of the most common types of wear, which makes abrasive wear resistance very important in many industries. The hardfacing is considered as useful and economical way to improve the performance of componentssubmitted to severe abrasive wear conditions, with wide range of applicable filler materials. The abrasive wear resistance of the three different hardfaced coatings (two iron‐based and one WC‐based), which were intended to be used for reparation of the impact plates of the ventilation mill, was investigated and compared. Abrasive wear tests were carried‐out by using the scratch tester under the dry conditions. Three normal loads of 10, 50 and 100 N and the constant sliding speed of 4 mm/s were used. Scratch test was chosen as a relatively easy and quick test method. Wear mechanism analysisshowed significant influence of the hardfaced coatingsstructure, which, along with hardness, has determined coatings abrasive wear resistance.
