研究了不同压力下氧化铝空气研磨对丙烯酸树脂与铸造合金粘结的影响。由银-钯-铜-金（Ag-Pd-Cu-Au，Castwell M.C.12）合金和钛-铝-铌合金（Ti-6Al-7 Nb，T-Alloy坚韧）铸造圆盘试样（直径8和10 mm）。在不同气压（0未研磨、0.1和0.6MPa）下用氧化铝颗粒（50-70微米）对盘进行空气研磨。盘对粘结在一起的三正丁基硼烷（TBB）引发的丙烯酸树脂，和剪切粘结强度进行了测定之前和之后的热循环。对于Ag-Pd-Cu-Au合金，结合强度从最大37.1 MPa变化到最小3.6 MPa，而与Ti-6Al-7 Nb合金的结合强度范围为34.7 MPa到0.1 MPa。0.6 MPa压力磨损的试样记录最大的热循环后的粘结强度（21.7 MPa和17.9 MPa），和未磨损的试样表现出最低的强度（3.6 MPa和0.1 MPa）的两种合金。在相同的空气研磨条件下，Ag-Pd-Cu-Au合金的热循环后结合强度高于Ti-6Al-7 Nb合金。可以得出结论，空气压力为0.6 MPa的氧化铝空气磨损是有效的，在增强TBB引发的树脂连接到合金的保持特性。
This study examined the effect of alumina air-abrasion with different pressure on bonding between an acrylic resin and casting alloys. Disk specimens (8 and 10 mm in diameter) were cast from a silver-palladium-copper-gold (Ag-Pd-Cu-Au, Castwell M.C.12) alloy and a titanium-aluminum-niobium alloy (Ti-6Al-7Nb, T-Alloy Tough). The disks were air-abraded with alumina particles (50-70 microm) under different air-pressures (0 unabraded, 0.1, and 0.6 MPa). The disk pairs were bonded together with a tri-n-butylborane (TBB)-initiated acrylic resin, and shear bond strengths were determined both before and after thermocycling. Bond strength varied from a maximum of 37.1 MPa to a minimum of 3.6 MPa for the Ag-Pd-Cu-Au alloy, whereas bond strength to Ti-6Al-7Nb alloy ranged from 34.7 MPa to 0.1 MPa. Specimens abraded with 0.6 MPa pressure recorded the greatest post-thermocycling bond strength (21.7 MPa and 17.9 MPa), and unabraded specimens showed the lowest strength (3.6 MPa and 0.1 MPa) for both alloys. Post-thermocycling bond strength to the Ag-Pd-Cu-Au alloy was higher than that to the Ti-6Al-7Nb alloy under identical air-abrading conditions. It can be concluded that alumina air-abrasion with an air-pressure of 0.6 MPa is effective in enhancing retentive characteristics of the TBB-initiated resin joined to the alloys.
