Abstract
The invention discloses a wear-resistant high-hardness anticorrosive grinding body. The grinding body comprises the following raw materials in parts by weight: 20-40 parts of diamond micro-powder, 10-12 parts of cubic boron nitride, 5-10 parts of modified phenolic thermosetting resin, 2-3 parts of titanate, 15-20 parts of silicon carbide grain, 20-30 parts of modified alumina, 1-2 parts of silica powder and 1-2 parts of quartz sand, wherein the preparation process of the cubic boron nitride comprises the following steps: uniformly mixing 90-95 weight percent of hexagonal boron nitride and 5-10 weight percent of magnesium base alloy, and converting the obtained cubic boron nitride under the conditions of the temperature of 1980-2000 DEG C and the pressure of 4*10<6>-4.3*10<6>KPa. The wear-resistant high-hardness anticorrosive grinding body disclosed by the invention is anticorrosive, high in hardness, high in toughness and excellent in wear resistance.
Description
Technical field
The present invention relates to grinding element technical field, relates in particular to a kind of wear-resisting high-hardness corrosion-resistant grinding element.
Background technology
The requirement of modern mechanical processing and manufacturing and oil, the Performance and quality of geological prospecting industry to ultra-hard abrasive material improves constantly.Synthetic strong adaptability, the material that has high rigidity and toughness concurrently are the extremely valuable research directions in current abrasive substance field, have because grinding element is subject to perhaps sandstone, stiff fibre shape material etc. in use that matter is hard, the effect such as the medium of surface irregularity, cutting character and high temperature, impact, corrosion, can produce serious all kinds of abrasion loss, cause scrapping too early or losing efficacy, affect normal operation and the production schedule of equipment, at present corrosion-resistant, the hardness to grinding element, toughness and wear resistance require more and more higher.
Summary of the invention
The present invention proposes a kind of wear-resisting high-hardness corrosion-resistant grinding element, corrosion-resistant, hardness is high, good toughness, wear resisting property excellence.
The wear-resisting high-hardness corrosion-resistant grinding element of one that the present invention proposes, its raw material comprises by weight:
