一种用于1Cr18Ni9Ti不锈钢表面的搪瓷材料及其制备方法
摘要：
本发明提供一种用于1Cr18Ni9Ti不锈钢表面的搪瓷材料及其制备方法，该搪瓷材料是通过将包含以下组分的原料烧结而成的：二氧化硅39～42重量份，三氧化二铝12～14重量份，二氧化钛6～9重量份，氧化镁0.5～1重量份，氧化锌5～7重量份，氧化钙3～5重量份，氧化镍0.5～3.5重量份，三氧化二硼5～7重量份，氧化钠18～20重量份。本发明的搪瓷材料耐温性高，其耐温温度可达600℃以上，耐酸碱腐蚀性能相对优异，同时能够保证较高温度下搪瓷材料与1Cr18Ni9Ti不锈钢基体材料的良好匹配，能够有效防止搪瓷材料脱落的发生。
摘要（英）：

The invention provides an enamel material for 1Cr18Ni9Ti stainless steel surface and a preparation method thereof. The enamel material is prepared by sintering a raw material comprising the following ingredients: 39-42 parts by weight of silicon dioxide, 12-14 parts by weight of aluminum oxide, 6-9 parts by weight of titanium dioxide, 0.5-1 parts by weight of magnesium oxide, 5-7 parts by weight of zinc oxide, 3-5 parts by weight of calcium oxide, 0.5-3.5 parts by weight of nickel oxide, 5-7 parts by weight of boron trioxide and 18-20 parts by weight of sodium oxide. The enamel material provided by the invention has high temperature tolerance, the heat resistance temperature of the enamel material can be higher than 600 DEG C, the acid and alkali corrosion resistance is relatively excellent, the enamel material is guaranteed to be well matched with a 1Cr18Ni9Ti stainless steel base material under a high temperature, and the enamel material can be effectively prevented from dropping.
