纳米WC弥散强化孕镶金刚石钻头
Dispersion strengthened impregnated drill bits by WC nanoparticles
摘要
Abstract
In order to improve the drilling efficiency and serving life of impregnated diamond bits,WC nanoparticles were introduced into the matrix of traditional bit matrix.The matrix formula and preparation process were optimized to utilize the dispensation strengthening effect of WC nanoparticles, improving physical and mechanical performance of working layers.Indoor drilling experiments were carried out to compare the the enhanced and traditional bits.Results show that when adding 2.5wt% nano-WC into traditional matrix of impregnated bits,an enhanced bit is developed,with 24.93% faster drilling speed,28.91% longer service life and steadier process.关键词
