Abstract
A laminated coating film according to the present invention comprises at least one coating film (A) and at least one coating film (B) laminated on each other and has excellent abrasion resistance. [Coating film (A)] The compositional formula is (MSi)(BCN) (wherein M represents at least one element selected from the group consisting of a Group-4 element, a Group-5 element, a Group-6 element and Al; and a, x and y respectively represent the atomic ratios of Si, B and C), wherein a, x and y respectively fulfill the formulae: 0.05≦a≦0.35, 0≦x≦0.15 and 0≦y≦0.5. [Coating film (B)] The compositional formula is L(BCN) (wherein L represents at least one element selected from the group consisting of W, Mo and V; and x and y respectively represent the atomic ratios of B and C), wherein x and y respectively fulfill the formulae: 0≦x≦0.15 and 0≦y≦0.5.
