Method for manufacturing composite structure body

A method for manufacturing a composite structure body, comprising the steps of:

• forming composite fine particles by way of a process in which a surface of brittle material fine particles is coated with at least one type of ductile material;
• then by bombarding said composite fine particles against a surface of a substrate with a high velocity, forming an anchor portion biting said substrate surface;
• said brittle material fine particles are simultaneously distorted or fractured by impact of the bombardment;
• mutual rejoining of said composite fine particles is made through intermediary of a newly generated active surface formed by the distortion or fracture;
• and thereby forming a structure body, above said anchor portion, in which crystals of the brittle material and the crystals and/or microstructures of the ductile material fine particles are dispersed.

A method for manufacturing a composite structure body, comprising the steps of:

• arranging brittle material fine particles and ductile material fine particles on a surface of a substrate;
• exerting mechanical impact to the brittle material fine particles and the ductile material fine particles to form an anchor portion biting said substrate surface;
• said brittle material fine particles are simultaneously deformed or fractured by the mechanical impact;
• mutual rejoining of said fine particles is made through intermediary of a newly generated active surface formed by the distortion or fracture;
• and thereby forming a structure body, above said anchor portion, composed of a structure in which crystals of the brittle material and crystals and/or microstructures of the ductile material are dispersed.
