纳米改性Al2O3/TiB2/CaF2自润滑陶瓷刀具的切削试验研究
The experimental study on cutting test of nano-modified Al2O3/TiB2/CaF2self-lubricating ceramic tool
摘要
Abstract
Using nano-CaF2as a solid lubricant,three kind of nano-modified Al2O3/TiB2/CaF2self-lubricating ceramic tools with different contents of CaF2,ATF1,ATF5,ATF10,were prepared,and used in the 45 steel and 40Cr cutting tests.The influences on the relations between cutting temperatures and cutting powers,rake face friction factors,and cutting properties of different tools of CaF2contents and cutting temperature were studied,the morphology of tools' flank wear and rake wear were observed by SEM, proving nano-modified self-lubricating ceramic tools have self-lubricating properties,and explaining the mechanism of tools' self-lubricating.The results showed that the CaF2content and cutting temperature both have impacts on the self-lubricating properties of self-lubricating tool.In 45 steel cutting experiment,the cutting temperature was high,tools' CaF2contents were inversely pro-portional to their total amount of material removalis,tools' self-lubricating was not obvious.In 40Cr cutting tests,the cutting tem-perature was low,compared with that of ATF1,the friction factors of the rake face of the ATF5 and ATF10 cutting tools with high-er CaF2contents were significantly decreased,ATF10 tool whose CaF2content of the highest had the highest total amount of mate-rial removal,showing an obvious self-lubricating property and best cutting property.关键词
