Microstructural effects on the resistance to cavitation erosion of ZrO2 ceramics in water

Autor: Johannes Schneider, Jinjun Lu, Karl-Heinz Zum Gahr

Publikováno v: Wear. 265:1680-1686

The cavitation erosion behavior of three commercial ZrO 2 ceramics and one Al 2 O 3 ceramic as reference was investigated using a laboratory test with vibration-induced cavitation following the pattern of the ASTM standard G32-92. The purpose of this

Cavitation erosion of advanced ceramics in water

Autor: Karl-Heinz Zum Gahr, Johannes Schneider, Ulrike Litzow

Publikováno v: International Journal of Materials Research. 97:1372-1377

The performance of advanced ceramics under cavitation loading in distilled water was studied by using a laboratory test with vibration-induced cavitation following the pattern of the ASTM standard G32–92. The hardened and tempered martensitic steel

Effect of thermal oxidation on indentation and scratching of single-crystal silicon carbide on microscale

Autor: Klaus Pöhlmann, Karl-Heinz Zum Gahr, Bharat Bhushan

Publikováno v: Wear. 237:116-128

Indentation and scratching experiments were conducted on single-crystal SiC ceramic with and without thermal oxidation treatment, single-crystal Si and amorphous SiO 2 using a modified atomic force/friction force microscope with a sharp diamond tip.

Effect of Surface Microtexturing on Friction at Unidirectional Sliding Depending on Lubricant Viscosity

Autor: Karl-Heinz Zum Gahr, Mario Mann

Publikováno v: ASME/STLE 2012 International Joint Tribology Conference.

Effect of surface microtexturing with spherical dimples of 60 μm diameter on friction behaviour of steel 100Cr6/sapphire pairs was studied as function of lubricant viscosity. Tests were run at unidirectional sliding up to 0.30 m/s using a pellet-on-
