Synthesis And Tribological Property Of Nickel Base Composites Containing Jinchuan Cu-Ni Deposit

With the rapid development of China’s economy, the the domestic industrial mining waste,as well as various types of mine waste rock excretion also increased year by year, a lot offarmland, forests are occupied, and caused a great deal of pollution on the surroundingenvironment, to normal human life has brought a great deal of inconvenience and trouble.Various industrial mining waste and the types of mining waste rock has become an " outcast " inChina ’s industrial sector, but as time goes on, these " outcast " slowly into the eye, and these "outcast " in the industry and mines to be used, so that it becomes " waste " into treasure, hasbecome a hot issue in recent years, mineral sciences research.The data show that about30%of the primary energy due to friction and wear undueconsumption of about70%-80%of the mechanical parts are lost value because of the wearmaterial. Into the21st century, all kinds of construction machinery gradually development to thedirection of long-life, low energy consumption, and therefore a higher demand on the frictionand wear material. Therefore, to carry out high wear-resistant, high-strength friction materialdevelopment and research has important significance in today’s society industrial areas undercertain conditions on the special requirements of special materials.In this study, Jinchang City, Gansu Province, Jinchuan copper-nickel deposit, one of thewaste rock that does not have the industrial exploitation of the value of copper-nickel specialdepleted ore as the main raw material, accompanied electrolytic nickel powder and electrolyticchromium powder was prepared by a new type of mineral friction materials (nickel matrixcomposites), and compared to the friction and wear properties of pure nickel chromium alloymetal material with new mineral friction material, after a large number of experimental studies,determined and prepared to add a new copper-nickel ore minerals friction material.This paper, the use of X-ray fluorescence spectrometer, optical microscopy, small load Brinell hardness, WDW-200computer-controlled electronic universal testing machine the THT-temperature friction and wear tester, scanning electron microscopy, spectroscopy to study thedifferent content new copper-nickel slag mineral material microstructure, mechanical propertiesand tribological performance. Optimal optimal pressurization method I test several attempts todetermine the sintering mold and sintering process, and the results showed that, after the copper-nickel slag is added in pure nickel-chromium alloy material, fine grain of grain boundarypurification, the decrease in the density of the material, has been significantly improved in termsof hardness, bending strength decreased slightly, and a new type of mineral materials is muchsuperior than the original metal friction and wear properties of the material. According to theresults of all the data analysis to determine the new add5%by weight copper-nickel slag mineralmaterials the optimal formula material, and add5%by weight copper-nickel slag new mineralmaterial is an ideal wear-resistant materials and surface protective material, not only to reducethe material consumption of Jinchuan copper-nickel special lean ore this industrial waste rock,and makes more efficient use of, and effectively improve the local ecological environment, andcontribute to the local industry has stockpiles of the state system of industrial waste matterreduction. Throughout the trial preparation process is clean and free of carbon monoxide, carbondioxide and dust emissions, in line with the country’s " clean production and energy efficientpolicy of environmental protection requirements.
