摘要
介绍了金刚石工具中常用的金刚石表面镀钛和坑化处理等2种表面预处理技术。并对比分析使用镀钛、坑化处理的金刚石钻头和常规金刚石钻头在钻进钢筋混凝土时的效率和寿命。钻进实验证明:与常规金刚石相比,镀钛金刚石钻头寿命可以提高30%以上;坑化处理金刚石可以将钻头寿命和钻进效率分别提高35%和10%,并且能降低生产时的金刚石浓度,是目前发展较为迅速的一种工艺技术。
This paper introduces two kinds of diamond surface pretreatment technologies,namely titanium coating and pit treatment,which are commonly used in diamond tool manufacturing.The efficiency and life of 2 bits made of pretreated and conventional diamonds when drilling reinforced concrete are compared and analyzed.Drilling experiments show that compared with that of conventional bit,the life of the bit made of Ti-coated diamond can be increased by more than 30%,and that the service life and drilling efficiency of bits made of pit-treated diamonds are increased by 35% and 10%respectively with lower concentration of added diamond.Therefore,pit treatment is a rapidly developing technology at present.
