壳壳镀镍 - Ducta-Bright7a®
电子游艺棋牌先进的电镀技术是弹药和国防行业内的壳壳镀镍的领先供应商，提供称为Ducta-Bright7a®镍的专有延性镍系统。带Ducta-Bright7A®的壳体镀镍提供了几种主要优点，包括在枪械的所有动作中提高喂养，增强了传统黄铜的耐腐蚀性以及改善的化妆品和易于复印过程中的清理。镀镍外壳在储存期间不会像黄铜一样玷污，或者与皮革霍尔斯特或皮带袋等材料接触时。
直到Ducta-bright 7 a®proc的发展ess, nickel plating of shell casings often limited the number of reloads as compared to raw brass. It was claimed that nickel plating of brass shell casings “embrittled” the brass thereby making it less preferable for reloaders despite the ease of cleanup that nickel plating affords. In addition, ammunition engineers raised concern of using nickel plating in very hot +P or magnum loads – especially in deep-drawn casings – where it was thought that nickel plating of such loads could result in once-fired casing cracking or failures.
Such preexisting industry concerns conflict with the metallurgy involved in nickel plating of brass casings. Classic C260 cartridge brass (70% copper, 30% zinc) is not susceptible to hydrogen embrittlement nor is there any chemistry employed in traditional nickel plating processes that is known to embrittle brass such as ammonia. Due to repeated inquiries regarding these design concerns by engineers within the ammunition industry, Advanced Plating Technologies set forth to investigate nickel plating of brass casings further. The aim was to try and determine if these deleterious effects actually occurred and if they did, establish root cause and develop a system that would mitigate these deposit flaws.
The Ducta-bright 7a® nickel system was developed over a one year focused engineering study by APT’s engineering group to either prove or disprove the theory of brass embrittlement by nickel plating. Over 40 unique combinations of pretreatment, nickel plating and process variables were analyzed. The nickel plated lots were tested for function in a proprietary dynamic impact loading test developed by APT mechanical engineers – the JLB impact tester. During initial testing the data began to indicate that certain process variables could be adjusted to improve the durability and function of a nickel deposit on a brass shell casing.
在分析的40项试验中，从JLB的影响测试中出现了四个决赛批次。这些批次在现场射击试验中进行了测试，其中装载，烧制和重新装载，直到在重新装载过程中裂开的外壳。这种详尽的研究结果是7TH.很多，方法A被发现在功能上高于所有其他批次。此批次的过程参数成为Duta-Bright7A®过程。今天，在批判性商业和防御应用中，每周都在数百万套箱上存放了该镍系统。
壳体套管的镀镍提供了对原料黄铜的许多功能改进，包括：
- 在枪械的所有行动中增强喂养;
- Improved corrosion resistance for reliability during extended storage or aggressive field applications;
- 储存在皮革燕子或袋子里时，无牙黄色;
- 烧制后易于清理以在重新加载之前去除碳和烟灰。
过去，弹药工程师必须权衡镀镍外壳的潜在益处，抵抗热负荷裂解或故障的风险，如+ P或Magnum应用。毫无疑问，现代临界防御和+ P负载压力黄铜套管，比以往任何时候都在临界防御应用中的镀镍黄铜外壳的可靠性在设计考虑中至关重要。此外，Avid Reloaders不得不称量清洁镀镍的黄铜套管，以防止镀黄铜所提供的重新装载的减少。
Advanced Plating Technologies’ proprietary Ducta-bright 7a® Nickel process eliminates these concerns for high-performance nickel plated brass casings applications and avid reloaders. The Ducta-bright 7a® Nickel process provides a lustrous nickel deposit that can withstand even the most aggressive +P loading and will afford virtually as many reloads as a raw brass casing. Simply put, there is no other nickel system available today that provides the functional and durability improvements as does Advanced Plating Technologies’ Ducta-bright 7a® Nickel process.
