Definitions
- a method for manufacturing a sliding member which adopts a powder metallurgy method to manufacture a bi-material or multi-material planar sliding member, at least including:
- the laid second powder material is Fe-based alloy powder or Fe-based mixed powder
- the laid first powder material is Fe-based self-lubricating material powder or Cu-based self-lubricating material powder.
- FIG. 1 is a schematic structural diagram of an interface construction template used in the methods of various embodiments of the present invention.
- FIG. 2 is a schematic diagram of the usage principle of the interface construction template adopted in the methods of various embodiments of the present invention.
- the material 2 and the first powder material 1 are removed, and after the interface construction template 3 is removed, the second powder material 2 and the first powder material 1 are individually metallurgically sintered to form a support material layer and a working material layer, a non-linear interface structure corresponding to the undulating structure shape of the interface structure template 3 is formed at the sintered interface of the support material layer and the working material layer.
- the laid second powder material 2 and the first powder material 1 are both non-bonded powders.
- Binder, interface structure template 3 selects a polyvinyl chloride sheet with a thickness of about 0.4mm, the degreasing temperature is 500°C, and the final sintering temperature of about 900°C is sintered for 3 hours according to the method of Example 2, and the maximum pressure applied during the period is 50MPa. Finally, a planar sliding part product with a density of more than 97% can also be obtained, and the non-linear interface structure at the material interface is uniform in shape.

Abstract
Procédé de fabrication d'élément coulissant, comprenant : la fabrication d'un élément coulissant plan bi-matériau ou multi-matériau, tel qu'un palier lisse d'une machine textile, en utilisant un procédé de métallurgie des poudres ; l'utilisation d'un second matériau en poudre en tant que matière première en poudre d'une couche de matériau de support, et l'utilisation d'un premier matériau en poudre en tant que matière première d'une couche de matériau de travail ; le dépôt des matériaux en séquence de telle sorte que le second matériau en poudre se trouve en dessous du premier matériau en poudre ; le placement d'une feuille qui est d'une structure ondulée et qui est constituée d'un matériau thermiquement décomposable entre le second matériau en poudre et le premier matériau en poudre en tant que gabarit de construction d'interface, le gabarit de construction d'interface pouvant être retiré entre le second matériau en poudre et le premier matériau en poudre au moyen d'un pré-frittage ou d'un dégraissage de dégazage, et lorsque le gabarit de construction d'interface est retiré, le second matériau en poudre et le premier matériau en poudre sont respectivement frittés de manière métallurgique pour former la couche de matériau de support et la couche de matériau de travail ; et la formation d'une structure d'interface non linéaire correspondant à la structure ondulée du gabarit de structure d'interface en forme au niveau d'une interface frittée de la couche de matériau de support et de la couche de matériau de travail. Le procédé ne nécessite ni le compactage séparé des poudres ni l'ajout d'une procédure de fonctionnement individuelle pour le traitement de l'interface.
