Abstract

The invention relates to a preparation method of a special flexible ceramic composite infiltration layer, which belongs to the technical field of a ceramic composite infiltration layer preparation method, and aims at solving the technical problem that a common hardening technology and a common anticorrosion technology can be only used for improving the abrasion resistance or the corrosion resistance of a metal surface. The preparation method provided by the invention is capable of simultaneously and greatly improving the abrasion resistance and the corrosion resistance of the metal surface. According to the technical scheme, the preparation method comprises the following steps of: a, washing a workpiece; b, preheating the workpiece; c, infiltrating the workpiece with ceramics; d, curing the workpiece at a low temperature; and e, drying the cured workpiece cleaned by clean water. After being processed by the method disclosed the invention, the workpiece has extremely high abrasion resistance, excellent corrosion resistance and good fatigue resistance, and only slightly deforms. The preparation method is suitable for processing the workpiece with high requirements on the abrasion resistance and the corrosion resistance and has a good effect.

Description

technical field [0001] The invention discloses a method for preparing a tough special ceramic composite infiltrated layer, belonging to the technical field of preparation methods for a ceramic composite infiltrated layer. Background technique [0002] The current common methods of preparing the infiltrated layer, such as ion sputtering, physical deposition, chemical plating, electroplating, spraying, melting, etc., all have the problem of the bonding strength between the molecules of the two substances. And usually the general hardening technology can only improve the wear resistance of the metal, and the anti-corrosion technology can only improve the corrosion resistance of the metal surface, and cannot greatly improve the wear resistance and corrosion resistance of the metal surface at the same time. Contents of the invention [0003] The invention overcomes the problems existing in the prior art, and the technical problem to be solved is: general hardening technology an...
