(6) Inorganic contamination, such as dissolved metals, can cause problems with the plating quality, as when bright dipping or chromate treatments will be used. Low-current electrolysis will remove many of the metallic contaminations. An insoluble metallic hydroxide such as Novalyte-PR, added at 1-2 fluid ounces per 100 gallons of plating solution, will usually make neutral the effects of this contamination.
无机污染，如溶解金属，会导致电镀质量出现问题，如将使用光亮浸渍或铬酸盐处理。低电流电解可以去除许多金属污染物。在每 100 加仑电镀液中加入 1-2 液盎司的不溶性金属氢氧化物（如 Novalyte-PR），通常可以中和这种污染的影响。
(7) Organic contamination is caused by oils, greases, or other contamination from parts not fully cleaned before they were put into the plating solution. Regular treatment of the solution with activated charcoal will usually remove organic contamination, but it could also remove some of the Novalyte 370-A brightener.
有机污染是由油、油脂或其他在放入电镀液前未完全清洁的零件所造成的污染。定期用活性炭处理镀液通常可以去除有机污染物，但也会去除部分 Novalyte 370-A 光亮剂。

对于渗碳零件，在 250-300°F 下至少烘烤 5 小时
2) For non-carburized low alloy steel parts over 180 ksi which were plated to agree with QQ-P-416, bake 3 hours minimum at 350-400°F
对于电镀符合 QQ-P-416 标准的 180 ksi 以上的非渗碳低合金钢零件，在 350-400°F 下至少烘烤 3 小时
3) If the parts have nonchromated post-phosphate treatment, do not bake above 400°F or damage to the coating could occur
如果零件经过非铬化磷酸盐后处理，烘烤温度不得超过 400°F，否则可能会损坏涂层
4) For parts to get solid film lubricant, you can bake the parts after you apply the lubricant. You can use the bake cycle as specified for the lubricant cure (SOPM 20-50-08) as a substitute for the bake cycle specified in Paragraph 4.J.(12)(b)1) or Paragraph 4.J.(12)(b)2), but be sure to obey the limits in Paragraph 4.J.(12)(b)3).
对于获得固体膜润滑剂的零件，可以在涂抹润滑剂后对零件进行烘烤。您可以使用润滑剂固化（SOPM 20-50-08）规定的烘烤周期来替代第 4.J.(12)(b)1)段或第 4.J.(12)(b)2)段规定的烘烤周期，但一定要遵守第 4.J.(12)(b)3)段中的限制。
5. BRUSH CADMIUM PLATING 电镀刷镉
A. General
通用
(1) Brush cadmium plating can be applied to copper alloys, nickel alloys, cobalt alloys, and ferrous alloys below 220 ksi.
刷镀镉可用于铜合金、镍合金、钴合金和 220 ksi 以下的铁合金。
(2) This paragraph is a summary of the procedure. Refer to BAC5849 for details about plating times, electrode preparation, and details for the different solutions used for surface preparation and plating.
本段为程序摘要。有关电镀时间、电极制备以及用于表面制备和电镀的不同溶液的详细信息，请参阅 BAC5849。
(3) Do not use this procedure to brush cadmium plate ferrous parts heat treated 220 ksi or above. Use the procedures in BAC5854 (SOPM 20-42-10) for ferrous parts heat treated 220 ksi or above.
请勿使用本程序对热处理 220 ksi 或以上的黑色零件进行电镀刷镉。使用 BAC5854 (SOPM 20-42-10)中的程序处理热处理 220 ksi 或以上的铁质零件。
B. Surface Preparation
表面处理
(1) Solvent clean or manually clean as specified in SOPM 20-30-03, if parts are greasy or oily.
若零件有油脂或油污，则按照 SOPM 20-30-03 的规定进行溶剂清洗或手工清洗。
(2) If necessary, remove scale and rust from all of the area to be brush cadmium plated. Use abrasive paper, a brush, or something equivalent. File, chip or sand smooth the rough metal edges if they could catch or tear the electrode covers. Blend the damaged area into the good plating with a file or sandpaper. Make the blends as long as possible. Wipe off unwanted material and contamination with solvent as specified in BAC5750 (SOPM 20-30-03).
如有必要，清除电刷镀镉所有区域的污垢和锈迹。使用砂纸、刷子或类似工具。如果粗糙的金属边缘可能卡住或撕裂电极盖，则用锉刀、切片或砂纸将其打磨光滑。用锉刀或砂纸将受损区域与良好的电镀层混合。混合的时间越长越好。用 BAC5750（SOPM 20-30-03）规定的溶剂擦去不需要的材料和污染物。
(3) Apply masks around the area to be brush plated to make a border approximately 1/8 inch wide around the damaged area. To decrease edge buildup or burns, use metallic tape (1/8 inch minimum wide) at the edges. Make electrical connection between this tape and the part. Use a conductive adhesive, or turn an edge of the tape under to make contact with the part. Be sure to give all other areas protection from the plating solutions.
在要电镀的区域周围涂上遮蔽物，使受损区域周围形成约 1/8 英寸宽的边界。为减少边缘堆积或灼伤，在边缘使用金属胶带（最小宽度为 1/8 英寸）。在胶带和零件之间进行电气连接。使用导电胶，或将胶带边缘向下翻转，使其与零件接触。确保所有其他区域不受电镀溶液的影响。
(4) For titanium surfaces, and optional for other substrates, blast the area with a slurry of 180-240 grit aluminum oxide and water, until the area is a constant color. Use air pressure of 50-115 psi, an air water gun, and a 1 to 15 gallon paint pressure pot that has a stirrer. Then flush off all grit with water and start to plate within 1 minute.
对于钛金属表面（其他基材可选），用 180-240 粗细度的氧化铝浆和水喷射该区域，直到该区域呈现恒定的颜色。使用 50-115 psi 的气压、空气水枪和带搅拌器的 1-15 加仑油漆压力罐。然后用水冲掉所有砂砾，在 1 分钟内开始电镀。
(5) For all surfaces but titanium, electroclean as specified in BAC5849. Or, as an alternative, blast clean the surface with the procedure for titanium in Paragraph 5.B.(4).
对于除钛以外的所有表面，按照 BAC5849 的规定进行电解清洁。或按第 5.B.(4)段中有关钛的程序喷砂清洁表面。
C. Brush cadmium plate with the procedure for Dip Feed Plating (Handheld Electrodes) in BAC5849.
按照 BAC5849 中的浸渍电镀（手持电极）程序刷镉电镀。
D. Post Plate Treatment
电镀后处理
(1) After plating, bake the parts as specified in Paragraph 4.H.
电镀后，按第 4.H 段的规定对零件进行烘烤。
(2) If post plate treatment is specified, refer to Paragraph 4.I. or Paragraph 4.J.
如规定进行电镀后处理，请参阅第 4.I 段或第 4.J 段。

类型2 铬酸盐和 类型3 磷酸盐镀层必须连续、光滑、无粉末。用布擦拭时涂层不得松动或脱落。
C. Unless specified by the overhaul instructions, the plating thickness must be Class 1 (0.0005 inch minimum) for all parts but fasteners. For fasteners, the plating must be Class 2 (0.0003 inch minimum). Unless specified, the plating must not be thicker than 0.0008 inch.
除大修说明规定外，除紧固件外，所有零件的电镀厚度必须为 1 级（最小 0.0005 英寸）。对于紧固件，电镀厚度必须为 2 级（最小 0.0003 英寸）。除非有规定，电镀厚度不得超过 0.0008 英寸。
D. Unless specified by the overhaul instructions, the thickness requirements are for only visible surfaces which can be touched by a ball 0.75 inch in diameter. The plating must be continuous.

(1) Aluminum parts must have no blisters or loose plating after the bake or boiling water soak.
铝质零件在烘烤或沸水浸泡后，电镀层不得有水泡或松动。
(2) For parts other than aluminum, do a test on the plating as specified in BSS7235 after the supplemental treatment and bake. The layer must stay tightly bonded to the surface.
对于铝以外的零件，在补充处理和烘烤后，按照 BSS7235 的规定对电镀层做测试。镀层必须与表面紧密结合。
F. Corrosion Resistance (Type 2 plating only) — Give parts or specimens a salt spray test. Refer to BAC5701 for details. This includes items given Ultrachromate 300 treatment before the bake.
耐腐蚀性（仅限类型2 电镀） — 对零件或试样进行盐雾试验。详情请参阅 BAC5701。这包括在烘烤前进行超铬酸盐 300 处理的项目。
G. Do tests on samples at regular intervals to be sure of the plating quality. If the interval is not specified by this procedure or in BAC5701, use an interval that agrees with standard industry practices, your experience with the procedure, and to make sure you can find parts that could have bad plating. If BAC5701 gives a formula to calculate the interval, use it for your basic quality control plan.
定期对样品进行测试，以确保电镀质量。如果本程序或 BAC5701 中没有规定间隔时间，则使用符合标准行业惯例、您的程序经验的间隔时间，并确保您能找到可能电镀不良的零件。如果 BAC5701 提供了计算间隔时间的公式，请将其用于基本质量控制计划。
