A turbomachinery component includes a substrate having a surface, the surface being a material consisting essentially of at least one compound having the chemical formula M<SUB>n+1</SUB>AX<SUB>n</SUB>, wherein M is at least one early transition metal selected from groups IIIB, IVB, VB, and VIB, A is at least one element selected from groups IIIA, IVA, VA, VIA, and VIIA, X is one or both of carbon and nitrogen, and n is an integer between 1 and 3. The component is made by forming a compact and sintered substrate with the material, or by coating a substrate with the material.
