Portable hardness testers produced by TX Company, such as Barcol Hardness Tester, Rockwell Hardness Tester, Brinell Hardness Tester and Magnetic Hardness Tester, can be used to test the hardness of aircraft engines and aircraft structural parts, such as turbine blades and turbines, and can find out the defects and problems in materials in time, providing important basis for the maintenance and repair of engines. Aircraft engine structure repair manual stipulates that some components and spare parts are not allowed to be disassembled, and many other components are very difficult to disassemble, so it must be solved by portable hardness tester. For example, if the aircraft engine is on fire, it is necessary to determine the affected area of the fire through hardness test, so as to determine the repair scope.
