Specific embodiment:
Invention is described in further detail below with reference to drawings and Examples:
Referring to shown in accompanying drawing 1~2, this kind is used for the erosion case of gas/solid erosion device, it is characterised in that:The erosion case and bag A U-shaped thermal-insulating body 9 being arranged on support 1 is included, the front opening of thermal-insulating body 9 is close with the hermatic door 4 with handle 5 Envelope, between hermatic door 4 and the edge of thermal-insulating body 9 sealing strip 3 is provided with, and is provided with to thermal-insulating body 9 in the upper end of thermal-insulating body 9 The thermocouple 10 of temperature control is inside carried out, dividing plate 19 is provided with thermal-insulating body 9 and the inner space of thermal-insulating body 9 is divided into into working area 17 and the thermal treatment zone 20, two regional spaces are mutually blocked and seal, and are provided with around the thermal treatment zone 20 for working area 17 The calandria 18 that heated of space, through hole is machined with the back-end central of thermal-insulating body 9, main shaft 12 passes through axle envelope assembly 11 are arranged in through hole, and one end that main shaft 12 is located in thermal-insulating body 9 is located in working area 17 and is provided with by clamping screw 6 The vertical rotating turbine disk 7, is provided with the fixed seat 21 for fixing sample 8, the number of fixed seat 21 on the vertical rotating turbine disk 7 Amount up to six, main shaft 12 is located on the one end outside thermal-insulating body 9 and is provided with small belt pulley 13 and is installed by bearing block 14 On support 1, small belt pulley 13 is connected by V belt 15 with the main pulley 16 on the motor 2 of the bottom of support 1 To drive main shaft 12 to rotate, the rotation of main shaft 12 can drive sample 8 on the vertical rotating turbine disk 7 in working area 17 The sand grains contained in working area 17 is rotated and stirs, the sand grains for seething forms erosion to sample 8.
During test, first by numbering of weighing after the fully solidification of sample 8 for carrying out coating, sample fixed seat 21 is symmetrically mounted on On, and Adjustment Tests angle;It is evenly laid out on the base plate of erosion room after the sand grains of the granularity needed for test is weighed, close case Door 4 is simultaneously locked, and prevents sand and dust from leaking;The starting device after the parameters such as control system setting speed, temperature, time.Treat temperature After reaching setting numerical value, buncher 2 starts running.Because the high speed of the turbine disk 7 and sample fixed seat 21 rotates, in erosion room Produce huge air-flow.Sand grains is taken up by air-flow and is spread in whole casing, i.e., produce friction with the sample 8 of high-speed rotation, is led Test sample face coat generates attrition.End to be tested, after temperature drop, sand dust dissipate, can open chamber door 4.Will Sample order is removed, and is dried up after clear water flushing, cleaning surface dirt, is weighed.Weight change before and after comparative test, is tested As a result, erosion test is completed.
Compared with prior art, erosion case of the present invention has simple structure, esy to use, safe and reliable, work Various metals and nonmetallic coating, the erosive wear resistance of coating fast and accurately can be made evaluation by the characteristics of making efficiency high.
