Increasing Saw Resistance to Wear by Sharpening Interruption Abrasive Circles

Effect of Abrasive Particle Size on Abrasive Wear Resistance in Otomotive Steels

If one of the surfaces which are in touch is rough and hard, it chips the other surface due to relative motion or touching forces. The wear is called two-body abrasive wear. If there are free abrasive particles between the two bodies, the wear is called three-body abrasive wear. The free abrasive particles may be external material dust or the remains of chipping. Usually, the wear starts as a t...

Increasing of Machine Parts Wear Resistance by Nanostruсturing

This paper presents the scientific rationale for the use of a new generation of functionally graded nano-(L = 50-500 nm) based on the Al-N, Ti-N, Ti-C, Al-O and Mo-S nanolayers (l = 1-10nm) on steel to improve durability for operation in extreme operating conditions of parts and units of machines and mechanisms

THE EFFECT OF HEAT TREATMENT ON ABRASIVE WEAR RESISTANCE OF Fe-34Cr-4.5C%WT HARDFACING ALLOY

Abstract: Hardfacing is one of the most useful and economical ways to increase the service life of components subjected to abrasive wear. Iron based hardfacing alloys have long been considered as candidate coatings for wear-resistant applications in industry. In the present work two layer of Fe-34Cr-4.5C%wt hardfacing alloy was deposited on ASTM A36 carbon steel plates by SMAW method. The m...

Abrasive wear of enamel by bioactive glass-based toothpastes.

PURPOSE To determine the abrasivity of a 45S5 bioactive glass based toothpaste on enamel as a function of the particle size and shape of the glass. METHODS 45S5 glass was synthesized ground and sieved to give various particle sized fractions < 38, 38-63 and 63-110 microns. Two different grinding routes were used: percussion milling and ball milling. The glass powders were formulated into toot...
