**2. Materials and Methods**

In this study, WDB620 (Figure 1) was selected as the material of the moving jaw plate, and then the ceramic powder was laser-cladded on the surface of the moving jaw plate. The contents of various chemical components of ceramic powder are shown in Table 1 [22–25].

The cylinder sample after cutting is installed on the friction electronic tester and closely contacts with the ring. The material of the ring is 40Cr, the loads of the cylinder sample are 100, 200, 300, 400, 500, and 600 N, and the rotation speed of the ring is 2000 r/min. The test scheme was carried out according to Table 2.


Through the thermocouple temperature sensor used to collect the temperature of the cylinder sample (Figure 2), the collected temperature of each point is counted.

The model of the cylinder-ring was built in UG (Figure 3). (UG is an interactive computer-aided design and computer-aided manufacturing software, which has powerful functions and can realize the construction of various complex entities and models. It is mainly used in the product development fields of mechanical product modeling design, structural design, part assembly design, mold design, numerical control programming, design analysis, etc.) The radius difference between the two concentric circles is 230 mm [26–30], and it is added to the creator in FEPG in the form of x\_t (Figure 4). The material of the setting ring in FEPG is 40Cr, the inner part of the cylinder is WDB620 (movable jaw plate

material), and the outer part is laser cladding ceramic powder. The specific physical parameter settings of the cylinder-ring are shown in Table 3 [31–34].
