Abstract
Abstract A single step method of forming a composite of ductile niobium particles within a matrix of brittle niobium aluminum is taught. The method involves completely ablating the end of a rod of a niobium aluminum intermetallic with a laser beam to form a plume of vaporous and particulate material and depositing the ablated material on a receiving surface disposed proximate the rod end being ablated. A surface composite structure is formed in a single step and has ductile particles within a brittle matrix.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
70 words
A method for making a composite film having an intermetallic compound matrix and particulate metal inclusions embedded in the matrix which comprises providing a laser target of intermetallic compound forming material, providing a film receiving surface, directing laser energy at the target to form a plume of ablated target material, and condensing the ablated material onto the receiving surface, and thereby forming the intermetallic compound matrix and the particulate inclusions.
Claim 2
Independent Claim
70 words
A method for making a composite film having an intermetallic compound matrix and particulate metal inclusions embedded in the matrix which comprises providing a laser target of intermetallic compound forming material, providing a film receiving surface, directing laser energy at the target to form a plume of ablated target material, and condensing the ablated material onto the receiving surface, and thereby forming the intermetallic compound matrix and the particulate inclusions.
Claim 3
Dependent Claim
34 words
The method of claim 1 wherein the target is a niobium-aluminum intermetallic compound material and composite is a film of niobium-aluminum intermetallic compound having ductile particles of niobium embedded therein as the particulate inclusions.
