This paper defines the wear process of rollers made of 20Cr4. Rollers with a diameter of
1000 mm were installed in a roller press used for the production of drop-shaped briquettes …

Gear manufacturers must make decisions about the manufacturing materials and superficial
treatments. The best performance as to a type of failure should be evaluated. However, it is a …

This study presents and discusses the friction, wear and extreme pressure behavior of
nanoparticles suspended in a gear base oil. Zero, 0.5, 1 and 2% wt diamond and Zinc Oxide …

DD6 single-crystal superalloy is a crucial structural material widely employed in aerospace,
energy, and petrochemical industries. High-temperature creep resistance is a critical …

Introduction: Spur gears are important for transferring motion and power among shafts. The
surface characteristics of these gears are important for their life and smooth operation. To …

This work presents a comparative study of the surface characteristics of spur gears produced
from cryotreated and untreated hobs at various cutting speeds and feed rates kee** …

The paper presents the results of experimental studies on abrasion resistance of Hardox
500 steel and 20MnCr5 steel subjected to thermo-chemical treatment. These types of steel …

Industrial practice often prescribes cleaning of steel surfaces prior to welding with shot
blasting. Shot blasted components have been considered free of residual stresses. Hence …

In this paper the laboratory tests on the selected steel for cementation 20MnCr5 was
perfomed. The influence of the contact load resistance to the adhesion wear of high …

Carburization is a thermo-chemical treatment generally employed to enhance the surface
(wear) properties of low carbon steels. The recent carburization studies also focus …
