Identification of wheel wear equation in abrasive cut-off operation by GMDH.

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...

Effect of Abrasive Size on Wear

Modelling Friction and Abrasive Wear of Elastomers

In order to properly model the friction and wear of elastomer materials, it is essential to understand some specific mechanical and tribological features. Mechanical characteristics of elastomer materials are different from those of metals and other relatively hard materials. Elastomers can bear large deformations, the stress-strain curves are non-linear, time and temperature dependent. When th...

Wear of denture teeth by use of metal plates. Part 2: Abrasive wear of posterior teeth.

An in vitro study was conducted to evaluate the abrasive wear resistance of high-strength denture teeth (HS teeth). Eight types of specimen were used in the experiments; 3 types of HS teeth, 3 types of conventional plastic denture teeth (PL teeth), porcelain teeth and metal teeth. Sliding-induced wear tests were conducted by sliding the samples on a metal plate. The abrasive wear resistance of ...

An Investigation of Surface Quality Cut by Abrasive Water Jet

As abrasive water jet (AWJ) starts to be used in industry, especially in aerospace and automotive industries extensively, getting high quality surface has become a major requirement. Being a promising non-traditional cutting process, AWJ is holding several deficiencies, which limits its extensive applications dramatically. One of the deficiencies is striation marks presented on AWJ cutting surf...
