Embodiment Construction

[0073] Said figure shows different arrangements corresponding to the steps of the method for obtaining a part P having self-healing properties, the part P being composed at least of a first metal 1 having a first melting temperature T1 and having a second melting temperature T2 is made of the second metal 2, the second melting temperature T2 is lower than the first melting temperature T1.

[0074] These characteristics will be known according to the present method of the invention, said method comprising the following steps:

[0075] a) positioning and fixing the structure S made of the second metal 2 in the mold M1, M2 so that the structure S is positioned in the part P at a predetermined fixed position;

[0076] b) filling the molds M1, M2 with the first metal 1 to complete the part P;

[0077] c) Extract part P.

[0078] Step a) can be achieved by fixing the structure S directly to the mold M1, M2, for example as Figure 1 to Figure 4 as shown, or as Figure 5 to Figure...

Abstract

A method of obtaining a part P having self-healing properties, made of at least a first metal 1 having a first melting temperature T1 and a second metal 2 having a second melting temperature T2, said second melting at a temperature T2 lower than said first melting temperature T1, the method comprising the steps of: a) arranging and fixing a structure S made of said second metal 2 into a mold M1, M2 such that the structure S is arranged in said a predetermined fixed position in the part P; b) filling said molds M1 , M2 with said first metal 1 to complete said part P; c) extracting said P part. The invention also relates to the part obtained with said method and to the method for repairing cracks in said part P.

Description

technical field [0001] The present invention relates to a method for obtaining parts with self-healing properties, and more particularly to parts comprising low-melting reinforcing materials such that the parts can be obtained by heating the reinforcing material to a temperature below the melting point of the base metal alloy (but enough to melt the reinforcement), fill cracks or defects to make repairs. Background technique [0002] The present disclosure covers the internal structure and processing of self-healing metals, including metal matrix composites that exhibit self-healing behavior. When these "self-healing" materials crack or become damaged, a healing agent can be introduced into the damaged area to "heal" the damage. [0003] The self-healing system after suffering damage examines the possibility of restoring a substantial proportion of the properties of the raw material through the self-healing process. Such damage may be caused by micro-cracks, voids or crack...
