一种合金增材的耐磨管道
技术领域
本发明涉及增材金属耐磨管技术领域，特别涉及一种合金增材的耐磨管道。
背景技术
耐磨管输送已经遍及电力、冶金、煤炭、石油、化工、建材、机械等行业，并高速地发展着，耐磨管的磨损是一种普遍存在的现象，凡两个物体相互接触并有相对运动的表面都会发生磨损，管道磨损是指管道材料受到流动水和小而松散的粒子冲击时，材料表面引起的脱离或转移而造成的损伤破坏的磨损现象。
现有的耐高温耐磨管道，在使用的过程中虽然具备耐磨的特性，但是缺乏高耐磨、高硬度、耐冲击、抗腐蚀的特点，且为了减少成本和制造零件的复杂性，因此有必要提出一种合金增材的耐磨管道来解决上述问题。
发明内容
本发明针对以上问题，提出一种合金增材的耐磨管道来解决上述问题。
本发明是这样实现的，一种合金增材的耐磨管道，包括：耐磨管，所述耐磨管包括底层和耐磨层，所述耐磨层包含以下质量百分比含量的元素；C 3.0-5.5wt％，Si 0.3-2.5wt％，Mn 0.3-2.5wt％，Cr 15-30wt％，S ≤1.0wt％，P ≤1.0wt％，Fe合金粉末根据需要添加，以上各元素的质量百分比总和为100％。
为了使底层中的碳钢和高耐磨合金成分复合在一起达到冶金结合，且保证总厚度在10mm内，作为本发明的一种合金增材的耐磨管道优选的，所述底层材质为碳钢，且厚度为8mm-20mm。
为了增加该耐高温耐磨管道的耐磨性，和对4mm-10mm之间不同厚度耐磨层的硬度进行检测，作为本发明的一种合金增材的耐磨管道优选的，所述耐磨层的厚度为4mm-10mm，且耐磨层结构以针状的碳化铬合金金相组织实现耐磨功能。
为了用合金粉末增材的方式将该耐高温耐磨管道进行制备，作为本发明的一种合金增材的耐磨管道优选的，所述增材耐磨管通过冶金结合增材方式，将碳钢和高耐磨合金成分复合在一起制备而成。
为了对该增材耐磨管的耐磨度和硬度进行检测，作为本发明的一种合金增材的耐磨管道优选的，包括以下步骤：
步骤1、样品准备；
将如权利要求1所述的增材耐磨管切割取样平整展开，将样品焊接在厚度≥100mm的测试块上。
步骤2、打磨抛光；
将样品表面进行磨光磨平，最后用5000目以上超细砂纸抛光。
步骤3、硬度测试；
用台式洛氏硬度仪多点（7个部位）测试取平均值。
为了增加检测的精度，作为本发明的一种合金增材的耐磨管道优选的，步骤2中所述的打磨抛光，采用多点钻取耐磨熔覆层。
为了进一步增加检测的精度，作为本发明的一种合金增材的耐磨管道优选的，步骤3中所述的硬度测试，将增材耐磨管用直读光谱仪进行合金成分检测。
与现有技术相比，本发明的有益效果是：
该种合金增材的耐磨管道，通过冶金结合增材方式，将碳钢和高耐磨合金成分复合在一起达到冶金结合，实现耐磨性能，根据抗拉强度测试，具有合金粉末增材的直管弯曲度和普通的直管弯曲度对比，具有合金粉末增材的弯管弯曲度和未具有耐磨层弯管弯曲度对比，明显该增材耐磨管抗拉强度、冲击韧性性能较高，根据采样打磨检测，耐磨层厚度越高，合金成分和硬度一般会越高，当耐磨层厚度≥4mm时，其硬度和成分即为增材成分，耐磨层越薄合金成分和硬度受到底材稀释影响越明显，由于耐磨层主要结构以针状的碳化铬合金金相组织实现耐磨功能，使得耐磨层表面有龟裂特征，和底材冶金结合后有韧性，打磨抛光，从而有效增加该增材耐磨管的硬度，因此该增材耐磨管具有高耐磨、高硬度、耐冲击、抗腐蚀的特点。
