A. General

通用

WARNING ：SOME OF THESE MATERIALS ARE FLAMMABLE AND TOXIC. CHEMICAL CONVERSION COATING POWDERS THAT TOUCH ORGANIC SOLVENT CAN CAUSE A FIRE.

警告：这些材料中有些是易燃和有毒的。化学转化涂料粉末接触有机溶剂会引起火灾。

(1) Class A, C, D, E or F coatings have an easy-to-see color that could be from light golden iridescent to gold-brown. Class B coatings have no color. You can use the color to help identify the coating, but clad parts with a Bonderite M-CR 600 Aero coating could have little or no color.

A 级、C 级、D 级、E 级或 F 级涂料具有易于观察的颜色，可从浅金色彩虹色到金棕色。B 级涂料没有颜色。您可以用颜色来帮助识别涂层，但使用 Bonderite M-CR 600 Aero 涂层的包覆零件很少或没有颜色。

(2) For tubing to get a complete, smooth coating on the interior surface, we recommend this forced-solution-movement procedure:

对于要在内表面获得完整、光滑涂层的管材，我们建议采用这种强力溶液移动程序：

(a) Pump the chemical conversion coating at a rate of up to 60 feet/minute to fill the tubes.

以高达 60 英尺/分钟的速度泵送化学转换涂层，使其充满管道。

(b) Stop the pump and keep the tubes below the surface of the solution in the tank for 85-95 seconds before removal.

停止泵送，使管道低于槽中溶液表面 85-95 秒后再移除。

以最高每分钟 60 英尺的速度泵送冷水以填充管道。

(d) Stop the pump and keep the tubes below the surface of the water in the rinse tank for a minimum of 4 minutes.

停止泵，使管道保持在冲洗槽内水面以下至少 4 分钟。

(e) Pump water through the tubes again, for 25-35 more seconds, before removal.

在移除之前，再次用泵将水流过管道，时间为 25-35 秒钟。

(3) For straight tubing smaller than 0.75-inch OD, use the forced-solution-movement procedure or as an alternative, this multiple-immersion procedure.

对于外径小于 0.75 英寸的直管，可采用强力溶液移动程序，或采用多次浸泡程序。

(a) Do a minimum of four immersions in each procedure step, but not in the chemical conversion coating solution. More than four immersions in the chemical conversion coating solution could cause powdery coatings.

每个程序步骤至少浸泡四次，但不浸泡在化学转换涂层溶液中。在化学转化涂层溶液中浸泡四次以上可能会导致涂层粉化。

(b) During each immersion, let the tubing completely fill with the treatment liquid before you remove it. Then let the liquid drain from the tubing. Do not put the tubing back into the liquid until the continuous flow from the tube becomes intermittent.

在每次浸泡过程中，要让管子完全充满处理液后再取出。然后让液体从管子中排出。直到管子中的持续流动变得断断续续，才可将管子放回液体中。

B. Type 1 (Immersion Application), Class A, B and C.

类型 1（浸入式应用），A 级、B 级和 C 级。

(1) Alkaline clean and rinse per BAC5749 (Ref SOPM 20-30-03) to get a water-break-free surface, unless the parts:

按照 BAC5749（参考 SOPM 20-30-03）进行碱性清洁和冲洗，以获得无断水的表面，除非零件：

(a) have a thermal spray coating.

有热喷涂涂层。

(b) are heat treated aluminum with heavy scale. Then you can alkaline etch per BAC5786, Type 2.

经过热处理的铝材有严重的结垢。然后可以按照 BAC5786 第 2 类进行碱性蚀刻。

(c) could catch solutions, as by open faying surfaces, swaged anodized fittings on tubes or ducts, or spot welded joints. Then use this procedure to get a water-break-free surface:

可能吸附溶液，如开放的焊接表面、管子或管道上的阳极氧化接头或点焊接头。然后使用本程序获得无断水表面：

NOTE: Check for water-break-free by flushing the cleaned surface with water. If the surface is clean (free of oils), water will make an unbroken layer and sheet off. If the surface is not clean, water will bead on the surface (droplets) or appear as patchy and non-uniform. The cleaned surface is considered water-break-free if the water is continuous for approximately 30 seconds.

注：用水冲洗清洁表面，检查是否无断水。如果表面清洁（无油污），水会形成一层无破损的薄层并从表面脱落。如果表面不清洁，水会在表面上形成水珠（水滴），或呈斑片状和不均匀。如果连续出水约 30 秒，则认为清洁后的表面无断水。

1) Rinse in cold water for 2 minutes minimum and examine for water breaks.

用冷水冲洗至少 2 分钟，检查是否有断水现象。

2) If there are water breaks, do one of these three steps until there are no water breaks:

如果有断水，请执行以下三个步骤之一，直到没有断水为止：

a) Manually clean per BAC5765, Method 3, or

按照 BAC5765 方法 3 手动清洗，或

b) Abrasive clean the surface with very fine Scotch-Brite pads and water. Rub only to scratch the surface. Be careful not to remove the clad surface, if the part has it. Then wipe with clean wipers or sponges wet with water. Wipe the area a minimum of two times until all sand and unwanted matter is gone.

使用极细的 Scotch-Brite 研磨片和水对表面进行研磨清洁。擦拭时仅划伤表面。如果零件有包层，小心不要擦掉包层表面。然后用干净的抹布或海绵沾水擦拭。至少擦拭两遍，直到沙子和杂质全部清除。

c) Manually clean per BAC5744 or manually deoxidize per BAC5765 with Solutions 16, 20, 42, or 43. Wipe or spray rinse to remove all cleaning or deoxidizing solutions, especially from areas that could catch solutions. Use only Solution 43 on BMS 8-289 aluminum foil.

按照 BAC5744 进行手工清洁，或按照 BAC5765 使用溶液 16、20、42 或 43 进行手工脱氧。擦拭或喷淋冲洗以清除所有清洁或脱氧溶液，尤其是可能吸附溶液的区域。在 BMS 8-289 铝箔上只能使用溶液 43。

(d) are Class C parts. Then alkaline etch per BAC5786.

(c) are aluminum tubing that was alkaline etch cleaned per BAC5876. Then deoxidize per BAC5786 for 10 minutes minimum, with the solution pumped through the tubing at a maximum flow rate of 60 feet per minute.

铝管按照 BAC5876 进行碱性蚀刻清洁。然后按照 BAC5786 将溶液以每分钟 60 英尺的最大流速泵入铝管，脱氧至少 10 分钟。

(d) are cast or welded parts. Then deoxidize per BAC5765 with Solutions 27A, 37, 38, or 39. Immediately rinse in water.

是铸造或焊接零件。然后用溶液 27A、37、38 或 39 按照 BAC5765 进行脱氧。立即用水冲洗。

(3) Put the parts in the applicable chemical conversion treatment solution for the time necessary to get a satisfactory coating. For tubing, use the forced-solution-movement or multiple-immersion procedures, as applicable. If air pockets cannot be prevented, turn parts only as necessary. Drain the parts up to 1 minute over the tank to minimize carry-over.

将零件放入适用的化学转换处理溶液中，浸泡必要的时间，以获得满意的涂层。对于管材，可酌情使用强力溶液移动程序或多次浸泡程序。如果无法防止气穴，只在必要时转动零件。在槽上方最多 1 分钟内排空零件，以尽量减少残留。

CAUTION ：TOO STRONG A WATER SPRAY COULD DAMAGE THE SOFT COATING.

7. QUALITY CONTROL 质量控制

A. Appearance

外观

(1) When examined without magnification, coatings must have no streaks, and must be continuous and have no powder or loose areas. The coating must have no breaks or scratches go through to the base metal, or other defects will make the part less serviceable. The size and number of contact marks must be kept to a minimum that agrees with good practice. Touchup of bare spots that occur at contact points is not necessary if the longest dimension of each spot is 0.1 inch or less. One bare spot can be up to 0.125 inch.

在不使用放大镜的情况下，涂层不得有条纹，必须连续，不得有粉末或松散区域。涂层不得有破损或划痕，否则会影响零件的使用性能。接触痕迹的大小和数量必须保持在符合良好操作规范的最低限度。如果每个接触点的最长尺寸为 0.1 英寸或更小，则无需对接触点上的裸斑进行修整。一个裸斑的最大尺寸可达 0.125 英寸。

(2) Color differences can occur because of the base metal, how it is examined and with different conditions of light. Differences in color on a part, or between different batches, are satisfactory.

由于基体金属、检查方式和光线条件的不同，可能会出现色差。一个零件上或不同批次之间的颜色差异是令人满意的。

(3) Class B: When examined without magnification, coatings must be without color.

B 级：在不使用放大镜的情况下，涂层必须无色。

(4) Class D: The coating color can be between a light golden iridescent to a gold brown, but must not be dark brown. Clad parts with Bonderite M-CR 600 Aero coating could possibly have no color, is satisfactory.

D 级：涂层颜色可从浅金色到金棕色，但不得为深棕色。覆有 Bonderite M-CR 600 Aero 涂层的零件可能没有颜色，但也是令人满意的。

B. All classes of unpainted chemical coating on aluminum and aluminum alloy parts must give the base metal protection from corrosion when given the 5% salt spray test specified in BAC5719.

铝及铝合金零件上所有等级的未涂漆化学涂层，在进行 BAC5719 规定的 5%盐雾试验时，必须能保护基体金属免受腐蚀。

C. Use only Bonderite M-CR 600 Aero for touchup and rework of parts or assemblies painted with BMS 10-20 primer. Other coating materials such as Bonderite M-CR Alcrm 1200 Aero, Bonderite M-CR 1200S Aero or Bonderite M-CR 1132 Aero can cause a powdery coating if used on BMS 10-20 primer.
