摘要
本文介绍用真空铸造法制造抗拉强度超过１０００ＭＰａ的高强度Ｃ／Ｍｇ复合材料。将Ｔ３００纤维经Ｃ－Ｓｉ－Ｏ梯度涂层处理后单向排布于型腔内，在真空下注入ＺＭ—５合金液，凝固后即得Ｃ／Ｍｇ复合材料零件或试样。试样的抗拉强度在纤维体积分数为０．３５时达１０５０ＭＰａ。本文讨论Ｃ－Ｓｉ－Ｏ梯度涂层对获得高强度复合材料的作用。
This paper deals with high tensile strength C/Mg composite with σ b > 1000MPa fabricated by vacuum casting. T300 fibers coated with C Si O gradient coatings are aligned in casting moulds, and then infiltrated with molten ZM-5 alloy under vacuum 4000Pa. The tensile strength of specimens containing fibers of 0.35 volume fraction reaches up to 1050MPa. The effects of C Si O gradient coating on tensile strength of composites are mainly discussed.
