Description
技术领域
本发明涉及一种燃气罩聚能环涂层及其制备方法，属于家用燃气灶领域。
背景技术
燃气灶是重要的厨房设备，随着对节能的重视程度不断增强，行业内普遍从燃烧器本身的结构考虑如何实现热效率的提升，以达到节能目的。但是，这种主动提升热效率的方法已经很难突破当前技术的瓶颈，热效率提升的幅度很有限。目前，有部分制造商为了提高燃气燃烧的热效率，在燃气灶的盛液盘上增加一个聚能环，该聚能环由聚能环形板制成，使得燃烧器被其包围，在燃气燃烧的时候就能减少流入到空气中的热量，从而提高燃烧的热效率。但目前的聚能环大都为铁基金属材料制成，其隔热性能较差，节能效果不够理想。有人提出了在聚能环中使用保温棉来减少热量损失，但其结构复杂，保温效果有限。另外，由于聚能环放置于燃烧器下方，使用时温度较高，铁基金属材料在高温下容易氧化，较易造成表面剥落烧损。
发明内容
针对现有技术的不足，本发明所要解决的技术问题是，提供一种燃气罩聚能环涂层，不但具有较高的发射率，同时该涂层还具有良好的耐高温、耐磨、耐腐蚀性能，延长聚能环的使用寿命。本发明同时提供了该涂层的制备方法。
为解决上述技术问题，本发明所采取的技术方案是，一种燃气罩聚能环涂层，其由喷涂在聚能环金属基体表面上的底层和喷涂在底层上面的发射涂层组成；所述底层为用等离子喷涂工艺喷涂氧化锆粉体或镍钴铬铝钇粉体得到的涂层。
所述底层涂层厚度为70-150um；
所述底层涂层粒径为15-45um。
所述发射涂层为用等离子喷涂工艺喷涂MoSi2（二硅化钼）粉体或硼化硅粉体得到的涂层；
所述发射涂层厚度为200-300um；
所述发射涂层原料粒径为40-60um。
一种燃气罩聚能环涂层的制备方法，包括下列内容：
首先处理好聚能环金属基体表面，然后在聚能环金属基体表面上喷涂底层和发射涂层；所述底层为用等离子喷涂工艺喷涂氧化锆粉体或镍钴铬铝钇粉体得到的涂层，粉体粒径为15-45um，涂层厚度为70-150um；所述发射涂层为用等离子喷涂工艺喷涂MoSi2粉体或硼化硅粉体得到的涂层，粉体粒径为40-60um，发射涂层厚度为200-300um。
应用本发明的方法，在聚能环金属基体表面上喷涂底层和发射涂层，具有以下效果：发射涂层具有良好的热辐射性能，使得聚能环具有较高的发射率，可以将到达聚能环表面的热量重新反射回去，减少热量损失；底层具有良好的耐高温性能，能保证聚能环在高温下长期使用，耐磨性能和耐腐蚀性能也得到了提高，能极大地延长聚能环的使用寿命。
