Description
技术领域
本发明涉及表面处理技术领域，特别涉及一种自动倾斜器导筒表面的耐磨防腐工艺。
背景技术
随着我国航空行业的高速发展，特别是在先进的航空发动机的关键制造技术中，对减轻发动机重量，提升发动机动能，保证发动机安全可靠的性能要求也越来越高。自动倾斜器导筒是直升机倾斜器的重要组成部分，要求强度高，密度小且耐磨、防腐、导热性能高。其一般采用7075铝合金铝合金制备。但铝合金受其自身高活性，易氧化，硬度低等的特点影响，导致其耐磨耐蚀性能较差。目前的普遍做法是在自动倾斜器导筒表面制备耐磨防腐涂层，从防护效果出发，要求涂层涂覆均匀，且与基材结合强度高，且还要求涂层自身耐磨耐腐蚀性能强，且涂层具有导热性好等一系列的要求。目前大多数自动倾斜器导筒表面采用碳化钨涂层，该涂层具有硬度高、防腐性能优异等优点，但受制备工艺限制及铝合金自身微观缺陷等影响，该涂层均匀性较差且局部与基材结合强度差，容易导致局部腐蚀而报废。
发明内容
为解决上述技术问题，本发明提供一种自动倾斜器导筒表面的耐磨防腐工艺，所制备的涂层均匀致密，且耐磨、防腐、导热性能优异。
本发明提供一种自动倾斜器导筒表面的耐磨防腐工艺，包括：
将自动倾斜器导筒表面预处理后，均匀涂覆一层炭黑；
采用激光器快速扫描涂有炭黑的自动倾斜器导筒表面，以对自动倾斜器导筒表面进行快速加热和冷却，使其熔凝强化；
采用等离子体增强化学气相沉积工艺在经熔凝强化的自动倾斜器导筒表面沉积非晶碳层；
采用爆炸喷涂工艺在自动倾斜器导筒表面的非晶碳层上再喷涂碳化钨钴涂层。
优选地，所述激光器为CO2激光器，所述激光器的激光功率为1500-3000W，搭接率10-20％，扫描速度为500-1500mm/min，激光宽带尺寸为长×宽＝20mm×1mm。
优选地，熔凝强化在载气流量为5-10L/min的惰性气体下进行。
优选地，采用等离子体增强化学气相沉积非晶碳层的工艺参数为：腔体气压为0.2-0.3GPa，沉积功率为200-250W，沉积负偏压为-100--200V。
优选地，爆炸喷涂时的飞行速度为800-1200m/s，制备所述碳化钨钴涂层的粉末为粒径为15-40μm的碳化钨钴颗粒。
本发明提供的自动倾斜器导筒表面的耐磨防腐工艺，先通过激光熔凝工艺改善铝合金的合金偏析、第二相尺寸过大、气孔、裂纹等冶金缺陷，从而有助于减少电偶腐蚀，且有助于后续涂层的均匀附着，提高后续涂层与铝合金基体的结合强度。再通过在铝合金基体与碳化钨钴涂层之间增加非晶碳层，以进一步提高基体与碳化钨钴涂层之间的结合强度。并且，非晶碳层自身具有类似金刚石的高硬度与高耐磨性，可显著提高复合涂层的耐磨性。

非晶碳层中间层有助于缓解铝合金基体和碳化钨钴涂层之间的热膨胀差，从而有助于提高铝合金基体与后续碳化钨钴涂层之间的结合强度。并且，非晶碳层自身具有类似金刚石的高硬度与高耐磨性，可显著提高复合涂层的耐磨性。
S150、采用爆炸喷涂工艺在自动倾斜器导筒表面的非晶碳层上再喷涂碳化钨钴涂层。
本发明实施例中，爆炸喷涂时的飞行速度为800-1200m/s，制备所述碳化钨钴涂层的粉末为粒径为15-40μm的碳化钨钴颗粒。
由上可知，本发明提供的自动倾斜器导筒表面的耐磨防腐工艺，复合涂层与铝合金基体的结合强度高，且涂层能均匀附着在铝合金基体表面，且涂层具有高耐磨、高防腐及高导热性能，满足航空行业对自动倾斜器导筒的使用要求。
