Title
(EN) METHOD FOR CARBURIZING CERAMIC SLIDING MATERIAL
(FR) PROCEDE DE CEMENTATION PAR LE CARBONE DESTINE A UN MATERIAU DE GARNITURE PATIN CERAMIQUE
Abstract
(EN)
A process for carburizing ceramic sliding material is disclosed. Ceramics (Al2O3, ZrO2, oxide series) are dipped into an HF solution so as to surface-treat them down to 0.01-100$g(m)m. The ceramic materials thus surface-treated are put into a quartz tube (2), and then, are transferred to a carburizing furnace (5). Then silicon and benzine are injected, and then, they are heated and cooled. Then resin treatment is carried out, and washed and dried, thereby obtaining a carburized sliding material in which carbon is impregnated down to 0.01-100$g(m)m. Thus the carburizing is carried out in a simple manner, and the sliding material such as Al2O3 and the like are made to have improved friction coefficient, and other improved properties.

La présente invention concerne un procédé de cémentation par le carbone destiné à un matériau de garniture patin céramique. Les céramiques (Al2O3, ZrO2, les séries d'oxydes) sont plongées dans une solution fluorhydrique pour réaliser un traitement de surface sur une profondeur de 0,01-100 $g(m)m. Les matériaux céramiques ayant subi ce traitement de surface sont ensuite placés dans un tube de quartz (2) puis transférés dans un four de cémentation (5). Du silicium et du benzène ayant été ensuite injectés, les matériaux sont chauffés puis refroidis. Après traitement à la résine, ils sont lavés et séchés ce qui donne un matériau de garniture patin céramique cémenté par le carbone, dans lequel le carbone réalise une imprégnation sur une profondeur de 0,01-100 $g(m)m. Il est ainsi possible de réaliser la cémentation par le carbone de façon simple, et le matériau de garniture patin tel que notamment l'Al2O3 ainsi réalisé présente un meilleur coefficient de friction, et d'autres propriétés améliorées.
