carbon steel (AISI1045) and ultra low carbon bainite steel. To compute the friction coefficient between the coating layer of wire and the surface of die for a specific lubricant, a series of finite element... four kinds of specimens, which consist of a substrate and a coating, as shown in Table 1. As the substrate, ULCB (Ultra low carbon bainite) and AISI1045 were used. ULCB is a non-heat treated steel......

tend to be round shape. In contrast, the coating without Ce addition appears to be dendrite with high aspect ratio of needle-like grains that are commonly seen in the typical thermal sprayed coating...-like microstructures as observed in Fig. 4(a) and the large number of small spherical/rod-like κ1 phase as shown in Fig. 4(b). 4.3 Hardness of as-cast alloy and coating Because the cooling time......
nickel coating; drawing; deformation-induced texture; microstructure 1 Introduction The nickel electrodeposited carbon steel sheet can be prepared by bilaterally electrodepositing nickel on low carbon steel sheet and its thickness is 1-20 mm. The grain size is in micrometer or nanometer [1-4]. The electrodeposited nickel coating becomes an important engineering material. It is found......
