Erosive wear characteristics of high-chromium based multi-component white cast irons

Delamination Wear Mechanism in Gray Cast Irons

An investigation of the friction and sliding wear of gray cast iron against chromium plated cast irons was carried out on a newly constructed reciprocating friction and wear tester. The tests were the first to be done on the test rig under dry conditions and at the speed of 170 cm/min, and variable loads of 20-260 N for a duration of 15 min. to 3 hours. The gray cast iron surfaces worn by a pro...

Casting Process Design and Wear Properties of a High Chromium Cast Iron Hammer

Article history: Received: 13.04.2015. Received in revised form: 13.07.2015. Accepted: 15.07.2015. In this article, both chemical composition and structure of a high chromium iron hammer head were designed and analyzed respectively. Also, the casting process was investigated and optimized through numerical simulation using commercial software View Cast. On the basis of numerical simulation and ...

Fatigue Behaviour of Synthetic Nodular Cast Irons

A. Vaško, L. Trško, R. Konečná, Faculty of Mechanical Engineering, University of Žilina, Žilina, Slovak Republic The paper shows the influence of charge composition on microstructure, fatigue properties and failure micromechanisms of nodular cast irons. The additive of metallurgical silicon carbide (SiC) in analysed specimens increases the content of ferrite in the matrix, decreases the size of...

Tribological Behavior of Reinforced and Unreinforced High Chromium Cast Iron

In this paper, the metal matrix composites containing 22 wt % Cr, 2.5 wt % C and 2 to 16  volume percent TiC were processed by solidifying Fe-Cr-Ti-C in which precipitation of titaniumcarbide and chromium carbide occurred. The microstructure and abrasion resistance of in-situ synthesized composites were compared with the unreinforced high chromium white cast iron (HCWCI) containing 22 w. t. % C...
