作为表征钛合金性能的系统研究的一部分，我们研究了一系列铸造Ti-Hf合金的可磨削性。在氩弧熔炼炉中制备了含铪量高达40质量%的合金钮扣。每个纽扣都是用牙科钛铸造机铸造成镁基模具；每种金属都做了三个样品。在测试之前，去除硬化的表面层。在牙科电动机头上用金刚砂轮在0.98 N下以5种不同速度磨削1分钟。可磨削性的评价是每分钟去除的金属体积（磨削速率）和去除的金属体积与砂轮材料损失的比例（磨削比）。数据采用方差分析。可磨性随含铪量的增加有增加的趋势，但随含铪量的增加可磨性无统计学差异。我们还发现，铪可以用来硬化或强化钛，而不会降低可磨性。©2005 Wiley期刊公司[J]生物工程学报，2006
As part of our systematic studies characterizing the properties of titanium alloys, we investigated the grindability of a series of cast Ti–Hf alloys. Alloy buttons with hafnium concentrations up to 40 mass% were made using an argon‐arc melting furnace. Each button was cast into a magnesia‐based mold using a dental titanium casting machine; three specimens were made for each metal. Prior to testing, the hardened surface layer was removed. The specimens were ground at five different speeds for 1 min at 0.98 N using a carborundum wheel on an electric dental handpiece. Grindability was evaluated as the volume of metal removed per minute (grinding rate) and the volume ratio of metal removed compared to the wheel material lost (grinding ratio). The data were analyzed using ANOVA. A trend of increasing grindability was found with increasing amounts of hafnium, although there was no statistical difference in the grindability with increasing hafnium contents. We also found that hafnium may be used to harden or strengthen titanium without deteriorating the grindability. © 2005 Wiley Periodicals, Inc. J Biomed Mater Res Part B: Appl Biomater, 2006
