Avaliação físico-química e mecânica de zircônia nitretada a plasma
(2015-05-11)
This paper presents the nitriding experimental investigation of partially yttria stabilized zirconia (3 mol%), in particular, plasma generated by radiofrequency (RF), using two distinct methods: i) plasma nitriding, by ...
Comportamento do atrito por indentação em nanoescala do aço-carbono AISI 1045 nitretado e pós-oxidado com diferentes nanocamadas de magnetita
(2016-05-18)
The friction phenomenon still does not have an understanding in fundamental terms. Such understanding would help clarifying the frictional energy dissipation during the interaction between atoms of two or more surfaces ...
Efeito do hidrogênio e mecanismos na pós-oxidação por plasma pulsado de ligas ferrosas nitretadas
(2014-06-03)
This work shows the hydrogen effect and the influence of processing temperature and time in the post-oxidation treatment by pulsed plasma on nitrided AISI 1045 ferrous alloy. The crystalline structure was analyzed by X-ray ...
