Embodiment Construction

[0028] Such as Figure 1 to Figure 5 shown, see figure 1 with figure 2 , the workpiece surface treatment method of self-propagating reaction synthesis technique of the present invention comprises the steps:

[0029] A. Engraving the surface 2 to be processed of the open-shaped object 1, wherein the engraving method of the surface 2 to be processed is: processing the surface to be processed with at least two grooves 3, preferably a plurality of grooves 3. Groove 3 is straight or curved. Multiple grooves 3 are parallel to each other, or refer to image 3 , Figure 4 with Figure 5 , a plurality of grooves 3 are perpendicular to each other and pass through to form a grid-like groove 3 . The cross-sectional shape of the groove 3 is rectangular, U-shaped, trapezoidal, V-shaped, reverse T-shaped, trapezoidal or dovetail-shaped.

Abstract

The invention discloses a workpiece surface processing method for a self-propagating reaction synthetic process, relates to a workpiece surface processing method, and in particular to a processing method for achieving the self-propagating reaction synthetic process on an opening-shaped object. According to the workpiece surface processing method for the self-propagating reaction synthetic process, the structure is simple, the cost is low, operation is easy and convenient, the control capacity on the self-propagating reaction synthetic process is high, and the self-propagating reaction synthetic process can be reliably applied to the opening-shaped object. The workpiece surface processing method for the self-propagating reaction synthetic process includes the following steps: A, a to-be-machined surface (2) of the opening-shaped object (1) is carved; B, the to-be-machined surface (2) is coated with a well-mixed self-propagating reaction coating material; C, the coating material is ignited to motivate a self-propagating reaction; and D, pressurization and heat preservation are carried out on a resultant of the reaction and the workpiece (1).

Description

technical field [0001] The invention relates to a workpiece surface treatment method, in particular to a treatment method for realizing a self-propagating reaction synthesis process on an open shape object. Background technique [0002] Self-Propagating High Temperature Synthesis (SHS), also known as Combustion Synthesis (Combust ion Synthesis --- CS), is a process that uses the exothermic heat of the chemical reaction to continue the reaction, and finally synthesizes the desired material or new technology for products. The products prepared by SHS technology have high purity, low energy consumption and simple process, and are especially suitable for the synthesis of composite materials, structural ceramics and functionally graded materials. [0003] At present, there are more than 500 kinds of compounds synthesized by SHS. The combination of SHS technology and densification technologies such as sintering, hot pressing, hot extrusion, explosion, surfacing and centrifugal ca...
