摘要： PURPOSE: A removable bond for abrasive tool is provided to be easily chemically and electrochemically stripped from the metal core of a recovered used tool to facilitate reuse of the core. Relative to conventionally bonded tools, the speed of stripping the novel bond is quick, and the stripped core has a smooth, clean surface which needs only minimal mechanical repair prior to reuse. CONSTITUTION: A removable bond for abrasive tool consists essentially of copper, tin and titanium. It can be brazed at temperatures below diamond graphitization and is chemically compatible with diamond. Hence, the bond is particularly useful for the manufacture of large diameter, super abrasive metal single layer abrasive wheels employed in the construction industry. The bond can be applied to the cutting surface of the abrasive tool as a uniform mixture of bronze alloy, titanium compound and copper powders. The powders is mixed with a liquid vehicle and applied as a paste. The method of brazing the bond incorporates heating the bond composition to a temperature at most about 880°C to melt the bronze alloy and titanium compound components, and raising the temperature to at least about 900°C to dissolve the copper. The bond can also include an about 10-200 mu m thick barrier layer of copper coating the cutting surface between the core and the bond composition.
摘要翻译：目的：提供用于研磨工具的可拆卸接合件，以容易地从回收的二手工具的金属芯化学和电化学剥离，以促进芯的再利用。相对于常规结合的工具，剥离新粘合的速度是快速的，并且剥离的芯具有光滑，清洁的表面，在再次使用之前仅需要最小的机械修复。构成：用于研磨工具的可除去的粘合剂基本上由铜，锡和钛组成。它可以在低于金刚石石墨化的温度下钎焊，并且与金刚石化学相容。因此，该结合对于制造建筑行业中使用的大直径超级磨料金属单层研磨轮特别有用。该结合可以作为青铜合金，钛化合物和铜粉末的均匀混合物施加到研磨工具的切割表面。粉末与液体载体混合并以糊状物的形式施用。钎焊粘合剂的方法包括将粘合组合物加热到最高约880℃的温度以熔化青铜合金和钛化合物组分，并将温度升高至至少约900℃以溶解铜。该粘结还可以包括约10-200μm厚的铜屏蔽层，其在芯和粘结组合物之间的切割表面。

摘要： A bond for, a metal single layer abrasive tool can be easily chemically and electrochemically stripped from the metal core of a recovered used tool to facilitate reuse of the core. Relative to conventionally bonded tools, the speed of stripping the novel bond is quick, and the stripped core has a smooth, clean surface which needs only minimal mechanical repair prior to reuse. The composition of the novel bond consists essentially of copper, tin and titanium. It can be brazed at temperatures below diamond graphitization and is chemically compatible with diamond. Hence, the bond is particularly useful for the manufacture of large diameter, superabrasive metal single layer abrasive wheels employed in the construction industry. The bond can be applied to the cutting surface of the abrasive tool as a uniform mixture of bronze alloy, titanium compound and copper powders. The powders may be mixed with a liquid vehicle and applied as a paste. The method of brazing the bond incorporates heating the bond composition to a temperature at most about 880 DEG C to melt the bronze alloy and titanium compound components, and raising the temperature to at least about 900 DEG C to dissolve the copper. The bond can also include an about 10-200 mu m thick barrier layer of copper coating the cutting surface between the core and the bond composition.
