Wear Mechanism of CBN Inserts During Machining of Bimetal Aluminum-grey Cast Iron Engine Block

Cutting Forces and Tool Wear Investigation for Face Milling of Bimetallic Composite Parts Made of Aluminum and Cast Iron Alloys

Bimetallic parts are used in many industries for weight and cost reduction of workpieces working under high loads and wear. One application for this type of composite material is in automotive industry. In this work the tool wear and cutting forces in the face milling of bimetallic parts made of aluminum and cast iron were investigated. A356 and GG25 alloys that are common materials for bimetal...

Enhancing Wear Resistance of Squeeze Cast AC2A Aluminum Alloy

The effect of squeeze casting process parameters on wear behavior of AC2A aluminium alloy was primarily investigated in this experimental study. Five process parameters, namely squeeze pressure, pouring temperature, die temperature, die material and compression time, each at four levels were chosen and sixteen experimental runs based on L16 orthogonal array were performed. From analysis of vari...

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...

effect of austempering heat treatment on strength properties and hardness of aluminum grey cast iron

in the present work, the effect of aluminum content, austenitizing temperature and austempering time and temperature on the mechanical properties and hardness of fe-c-al grey cast iron was investigated. for this purpose, three alloys containing 1, 2 and 4 weight percent of aluminum were provided. the tensile samples were austenitized at 850?c and 900?c for 120 min, followed by austempering proc...
