Abstract
The present invention is friction electrostatic method of measuring wear performance of metal material, and belongs to the field of metal material wear measurement. The method include making metal sample insulated from the ambient rub with abrasive, taking out electrostatic signal, amplifying the electrostatic signal and feeding to computer, and printing electrostatic change graph. During friction, the static electricity in the material will increase; and when the abrasive dust peels off, the static electricity in the material will decrease. Measuring the change in static electricity can reflect the abrasive process and measure the wear performance of metal material.
Description
Technical field: the present invention relates to the method for measuring metallic materials polishing machine, particularly a kind of method of utilizing frictional static measuring metallic materials polishing machine.
Background technology: traditional wear measurement is weight, the density by the measurement material, and the wear condition of material is determined in the variation before and after wearing and tearing as parameter, and this method can not be carried out dynamic tracking observation to wear process.
Invention constitutes: the objective of the invention is to: a kind of method of utilizing frictional static measuring metallic materials polishing machine is provided, utilizes this method can reach the purpose of measuring and judging the fret wear situation.
Content of the present invention: with the test button and the abrasive material friction of surrounding environment insulation, take out electrostatic signal from sample, electrostatic signal is amplified and the input computing machine, printer output static changes figure.
Compared with the prior art, the present invention utilizes material friction to produce the principle of static, by the variation of the friction static that produces in material and the abrasive wear process, directly reflects the state of fret wear.When material and abrasive material took place to rub stably in friction process, static can rise on the material, when wearing and tearing produce bigger abrasive dust and when material surface is peeled off, because abrasive dust has carried static charge, thereby will make the static on the material reduce.By measuring the variation of this static, can the dynamic reflection progress of material wear.
Embodiment: tested metal material is clamped on the anchor clamps of electrostatic dynamic abrasion test device, move back and forth, the platform friction that abrasive material is housed with rotation, when being rubbed, material surface produces static, friction velocity is fast more, static is high more, and the abrasive dust that friction produces wearing and tearing formation is thin more, and static is stable more, when the abrasive dust size increases, when wearing and tearing increased, static can reduce and occur fluctuation, therefore, electrostatic signal by electrostatic signal detectors measure fret wear changes, the state that can dynamic reflection goes out fret wear amplifies electrostatic signal and the input computing machine, changes figure by printer output static again.
