the aim of the present study was to investigate the effect of quenching and tempering temperatures on themicrostructure, mechanical properties and the wear characteristics of medium carbon-high chromium wear resistantsteel. in addition, the dominant wear mechanisms were studied. for this purpose, austenitizing and temperingtemperatures were selected in the ranges of 900- 1000 °c and 300- 500 °c...

The possibility of replacing the femoral head alone, in either solid or articular surface replacement form, during revision operations on metal-on-metal total hip replacements remains an attractive feature of such implants. In the present investigation, laboratory simulator studies of the influence upon volumetric wear of inserting a new femoral head, of introducing some head rotation, and of d...

Carbon-fiber-reinforced silicon carbide (C/C-SiC) composite is widely used as a friction material owing to its good performance, even though it is more expensive than metallic materials. The light C/C-SiC composite is an ideal candidate for weight reduction of frictional parts. In this study, the friction and wear behavior of C/C-SiC composite was assessed using a ball-on-disk friction tester u...

Since the initial research leading to the production of diamond composite materials, there have been several important developments leading to significant improvements in the properties of these superhard composite materials. Apart from the fact that diamonds, whether originating from natural resources or synthesised commercially, are the hardest and most wear-resistant materials commonly avail...

OBJECTIVES The primary aim of this research was to investigate the wear behavior and wear mechanism of five different veneering porcelains. METHODS Five kinds of veneering porcelains were selected in this research. The surface microhardness of all the samples was measured with a microhardness tester. Wear tests were performed on a ball-on-flat PLINT fretting wear machine, with lubrication of ...

The wear resistance of microfilled and conventional composite resins, was examined, using two sizes of abrasive particles for polishing. The mechanical properties of the composite resins were also studied and evaluated in relation to wear. Conventional composites showed much lower wear resistance than the microfilled resins. The amalgam and human enamel abraded with 10ƒÊm SiC particles, had str...
