Description
技术领域
本发明涉及复合涂层技术领域，具体涉及一种铝制工件表面的复合涂层及其应用。
背景技术
涡旋压缩机由固定的渐开线静涡旋盘和呈偏心回旋平动的渐开线动涡旋盘组成的可变压缩容积的压缩机，动涡旋盘及静涡旋盘作为涡旋压缩机中最重要的摩擦副，两者的材质、结构、表面涂层及啮合精度直接决定着压缩腔的密封性，气体的压缩量受影响最大，进而影响到整机的性能和可靠性。
目前绝大多数涡旋压缩机被应用到车用空调系统和空气压缩机系统中，车用空调压缩机及空气压缩机的工况和使用环境较为恶劣，其中无油润滑涡旋空气压缩机中只能依靠空气来对动涡旋盘和静涡旋盘进行冷却，因此要求动涡旋盘和静涡旋盘能快速降温。为提高泵体耐磨性及可靠性，动、静涡旋盘的材质大多为轻质、高强度、耐磨的高硅铸造或锻造铝合金，为避免摩擦副为相同金属时易产生粘着磨损的情况，为使压缩机的铝合金动、静涡旋盘的磨合期更短、啮合精度更高、耐磨性能更好，需对动、静涡旋盘的局部或全部表面涂覆硬质耐磨润滑复合涂层现有的复合涂层表面的单体润滑层大多为PTFE或MoS2或有机硅，而这些单体润滑层在高温重载下的耐磨性较差，膜层较厚，膜层的均匀性也不好，该单体润滑层脱落后会使涡旋压缩机中动涡旋盘和静涡旋盘的配合间隙加大，进而影响到涡旋压缩机的压缩性能。所以表面复合涂层的类型、表面粗糙度、硬度、结合力、均匀性和耐磨性等都会直接影响到压缩机整机的性能及可靠性。
现有专利申请号为200920106784.0，专利名称为铝制真空泵腔体改进结构的发明专利，公开了一种铝制真空泵腔体改进结构，包括铝制泵腔，所述铝制泵腔的内表面层为硬质阳极氧化铝层和填充设置在所述硬质阳极氧化铝层表面的聚四氟乙烯层，所述硬质阳极氧化铝层表面有多个微孔，其中所述聚四氟乙烯层密封填充设置在所述微孔内。该专利中的润滑涂层聚四氟乙烯在高温重载的工况下的失效比较严重，在预磨期会使冷冻机油发黑，未能使压缩机泵体在运行前期达到预磨的效果。
发明内容

其三是二硫化钨单体润滑层膜层薄，减少了涡旋压缩机动涡旋盘和静涡旋盘在工作过程中因复合涂层的单体润滑层磨损后而导致的泄露量，使冷量大幅提升，从而提升压缩机的压缩性能。
附图说明
图1为实施例1中动涡旋盘10设置本申请复合涂层的示意图。
图2为实施例1中静涡旋盘20设置本申请复合涂层的示意图。
其中，10为动涡旋盘，11为复合涂层，11a为动涡旋盘表面Al2O3基陶瓷硬质耐磨层，11b为动涡旋盘二硫化钨层，21a为静涡旋盘表面Al2O3基陶瓷硬质耐磨层，21b为静涡旋盘二硫化钨层。
具体实施方式
如图1、图2所示，在涡旋压缩机运行时，动涡旋盘10按照一定轨迹进行平动，并与静涡旋盘20按照设计好的配合间隙以相对的公转运动形成不断变化的多个月牙形压缩腔，空气或制冷剂气体在该月牙形压缩腔内完成吸气、逐级压缩及排气的过程，进而实现压缩空气或制冷剂气体的目的。所述动涡旋盘10和静涡旋盘20均采用铸造铝合金或锻造铝合金，再经过精加工得到高精度的动涡旋盘10和静涡旋盘20。所述动涡旋盘10表面以及动涡旋卷板12的全部或局部涂覆有动涡盘复合涂层11，静涡旋盘20以及静涡旋卷板22的全部或局部涂覆有静涡盘复合涂层21。
实施例1
如图1所示，对所述动涡旋盘10和静涡旋盘20的全部表面，生成Al2O3基陶瓷硬质耐磨层(11a,21a)，所述Al2O3基陶瓷硬质耐磨层(11a,21a)，可以由硬质阳极氧化工艺或者微弧氧化工艺得到。本实施例中使用硬质阳极氧化对动涡旋盘10和静涡旋盘20表面进行处理。所述硬质阳极氧化工艺符合《GB/T 19822-2005铝及铝合金硬质阳极氧化膜规范》。使用测厚仪测得所述硬质阳极氧化膜层的厚度为35μm。按照《GB/T 4340.1金属材料维氏硬度试验第1部分：试验方法》所述的测试方法，对所述硬质阳极氧化层上多个测试点进行维氏显微硬度测试，测得所述硬质阳极氧化层的维氏显微硬度在300HV-500HV之间，较铝合金基材的硬度有大幅的提高。用粗糙度测试仪对硬质阳极氧化层进行粗糙度测试，硬质阳极氧化层表面的粗糙度Ra≤1.5μm，进而改善了空气压缩机涡旋盘的耐磨性能。
为了降低涡旋压缩机中涡旋盘磨合初期的摩擦系数并填充阳极氧化层的微孔，在硬质阳极氧化膜层上进一步设置二硫化钨层(11b,21b)。所述二硫化钨层(11b,21b)的涂覆方法可以为手动喷涂法、鼓式喷涂法、浸涂法、浸涂-离心法、刷涂法或丝网印刷法的一种，也可以为磁控溅射法或射频磁控溅射法中的一种。本实施例中使用浸涂-离心法涂覆二硫化钨层(11b,21b)。配置二硫化钨浸涂液，其中颗粒度为0.2-1.5μm的二硫化钨占浸涂液总量的75.5％，粘结剂为环氧树脂占总量的24.15％，固化剂为芳族多胺化合物占总量的1.7％，增塑剂为邻苯二甲酸丁二醇酯占总量的1.74％，所述添加剂为石墨占总量的1.5％；为便于喷涂，使用丙酮作为稀释剂对配置好的二硫化钨浸液做进一步稀释，所述稀释剂占总量的5％。
为了保证二硫化钨层(11b,21b)的厚度为15μm左右，将浸涂中离心电机的转速调节为150r/min～450r/min,本实施例中选择300r/min，所述零部件在二硫化钨浸液中的时间为20min。完成浸涂后，在空气中自然干燥10min后再送入固化炉中进行加热固化处理，或在完成浸涂后直接使用输送装置送入固化炉中进行加热固化处理，固化温度为200℃，固化时间为30-120min。
对本发明的复合涂层进行力学性能测试，测得本申请的复合涂层可在50MPa高压或重载的工况下长期运行，相较普通二硫化钼层只能承受15-20MPa左右的负载有着很大的提升。除此以外，本发明的复合涂层还能在强氧化还原环境，如含有强酸、强碱的环境以及辐射功率高达180W的环境下正常工作。
本申请复合涂层中的二硫化钨层，减少了压缩机磨合初期的磨合时间，磨合时间与普通单一耐磨涂层Al2O3基陶瓷硬质耐磨层(11a,21a)减少了1/2以上。对该复合涂层进行摩擦系数测试，测得摩擦系数只有0.05，相比现有技术降低了5-15倍左右。使用测厚仪对复合涂层进行多点测试，其中厚度差值只有±0.5μm，膜层均匀性良好。本申请的复合涂层，与铝制金属件的结合力很强，通过ISO2409的划格法对复合涂层进行附着力测试，本申请的附着力级别为0级，常规技术方案的附着力级别只有1级。即使该单体二硫化钨层被磨耗掉，但其膜层较薄只有15μm，对压缩机动涡旋盘10和静涡旋盘20的配合间隙影响很小，减少了零部件因配合间隙增大而加大气体的泄露量，使冷量或空气的压缩量提升，以9000w功率压缩机为例，功率可提高600w，提升了压缩机的COP，压缩机的性能及可靠性得到提升。
实施例2
涡旋压缩机中还有十字滑环、上支架、活塞、汽缸、滚子或法兰盘等部件，在上述部件上同样可以设置本发明的复合涂层。可以使用硬质阳极氧化工艺或者微弧氧化工艺，在部件表面设置Al2O3基陶瓷硬质耐磨层。本实施例中对上述部件的表面进行微弧氧化，所述微弧氧化层的厚度为5-30μm，本实施例中上述部件表面氧化层厚度为15μm，微弧氧化层的维氏显微硬度在700HV-1500HV之间，较铝合金基材的硬度有大幅的提高，微弧氧化层表面的粗糙度Ra≤0.8μm，进而改善了空气压缩机涡旋盘的耐磨性能。
在所述微弧氧化层上设置有二硫化钨层，所述二硫化钨层的涂覆方法可以为手动喷涂法、鼓式喷涂法、浸涂法、浸涂-离心法、刷涂法或丝网印刷法的一种，也可以为磁控溅射法或射频磁控溅射法中的一种。本实施例中，所述二硫化钨层通过磁控溅射法或射频磁控溅射法在Al2O3基陶瓷硬质耐磨层表面设置。本实施例中采用磁控溅射法进行将颗粒度为0.2μm-1.5μm的二硫化钨直接沉积到上述部件表面，沉积的厚度为0.5μm，沉积完成后再对二硫化钨层进行退火处理，退火温度为300℃。
本实施例中涂覆的二硫化钨膜层较薄，仅有0.5μm，且该涂覆该二硫化钨层零部件可在-253℃-480℃的温度范围内正常工作，即使单体层二硫化钨层在压缩机或空压机运行过程中被磨损掉，还有部分二硫化钨填充在Al2O3基陶瓷硬质耐磨层硬质阳极氧化层或微弧氧化层的微孔之中，减小动涡旋盘10和静涡旋盘20上Al2O3基陶瓷硬质耐磨层表面的峰形摩擦副对功的损耗，提升压缩机的运行性能及可靠性。
