O Tempo de Corte com Discos Abrasivos Pode Ser Reduzido pelo Controle da Velocidade de Corte
(1997-12-01)
This work presents an experimental study on the life of abrasive discs in cut-off type operations with two conditions of cutting speed. The cutting time is shown with a comparative analysis of the cutting speed.

Load effect in abrasive wear mechanism of cast iron with graphite and cementite
(ELSEVIER SCIENCE SA, 2009)
In this study four irons were casted with different chromium and vanadium contents: 2.66% Cr, 5.01% Cr, 2.51% V and 5.19% V. Their microstructure is composed of: ledeburite, graphite and M(3)C carbides (cementite). ...

Objective: To evaluate the effect of fluoride (F) varnishes supplemented or not with sodium trimetaphosphate (TMP) on enamel erosive wear followed or not by abrasion in situ.Methods: Ten volunteers were selected and randomly ...
Abrasion resistance of direct and indirect resins as a function of a sealant veneer
(Indian Journal Of Dental Research : Official Publication Of Indian Society For Dental Research, 2014)
Abrasive wear is one of the most common type of wear that not only affect teeth, as also dental restorations. Thus to investigate one of the etiological factors as tooth brushing procedure is clinical relevant in order to ...
