Description
図5に示す変形例1では、パイプ部は、外側耐摩耗層62における積層された各第1耐摩耗層(62a~62c)の厚さが同じとなるよう設計されている。
本変形例2では、外側耐摩耗層が3層以上の第1耐摩耗層を有する。図6に示すパイプ部の外側耐摩耗層72では、4層の第1耐摩耗層(72a~72d)が積層されている。
図7に示す本変形例3では、外側耐摩耗層62の第1耐摩耗層(62a~62c)と同様に、内側耐摩耗層63の第2耐摩耗層(63a~63c)を着色し、色分けする。
図8に示す本変形例4では、変形例3と同様に、第2耐摩耗層(73a~73c)を色分けするとともに、内側耐摩耗層73の厚さを、外側耐摩耗層62よりも薄くする。
