【文章內(nèi)容簡(jiǎn)介】 disk material is 45 steel and the dimension of the experimental roll material is 10 mm 10 mm ，which is embedded on the periphery of the 1ower disk．(2)The materia1 of the drive shaft is 40Cr steel which is hollow for water cooling．The bearing block，the forcing equipment，and the balancing spring are also designed．For this purpose．The GP10C1 highfrequency induction apparatus is employed，and the induction power source and the parameters are listed in Table 1．The surface of the inverse upper disk is heated by the GP10C1 induction power source according to the theory of skin effect of electromagnetic induction heating．The induction coil is specially designed as a semicircle for a continuous heating of the inverse upper disk．The experimental setup for testing thermal wear including the heater and water cooling system of the disks is schematically illustrated in Fig．1．The conductor material is T1 or T2 pure copper tube and the dimension is 10 mm 1 mm. 2 ExperimentalTo test the validity of the machine performance．roll material of high speed stee1(HSS) was embedded in the 1ower disk． The chemica1 position of the roll material (mass percent)is listed in Table 2．The original hardness of the experimental material was HRC measured by HR150ARockwel1 hard meter．The worn amount of HSS rol1 materia1 under different loads and slipping rate was measured using the SARTORINS BSIIOS electronic balance after cleaning and drying．The morphology of the worn surface of the specimen was observed through a scanning electron microscope (PH ILIPS505)．3 Results and DiscussionThe wear ratio curve is presented in ，which indicates the wear ratio as a function of cycles for specimen in different slipping rates of S=%% and loads of = MPa．In the experiment，the temperature of the upper disk was900℃ ， at which the wear was most severe．However．a(chǎn) decrease in the thermal wear owing to the oxide layer did not occur in this exper
