摘要
以过热蒸汽为传热介质和保护性气体,在热处理温度为165℃、180℃、195℃、210℃,热处理时间为10h的条件下对日本落叶松木材进行高温热处理,研究日本落叶松木材在不同热处理温度下的表面显微硬度变化。结果表明,随着热处理温度升高,热处理材表面显微硬度逐渐升高,当热处理温度低于195℃时,木材表面显微硬度变化趋势不明显,当热处理温度达到210℃时,热处理材的表面显微硬度显著提高,变化率高达44.12%。
Larix kaempfer wood was heat treated at temperature of 165℃, 180℃, 195℃, 210℃, and duration of 10h, with the superheated steam as a heating medium and a shielding gas. The micro-hardness at different temperatures are studied. The results show that micro-hardness goes up with the temperature and increases. The micro-hardness change is not obvious, when the heat-treated temperature is below 195 ℃. The micro-hardness change is so remarkable as to 44.12%, when the heat-treated temperature is 210 ℃.
