什么是热喷涂？

<P align=center><FONT color=#003399><B><FONT face="Arial, Helvetica, sans-serif" size=5>什么是热喷涂</FONT></B></FONT></P>
<P><FONT size=4><FONT face="Arial, Helvetica, sans-serif" color=#ffffff>cccc</FONT><FONT face="Arial, Helvetica, sans-serif" color=#000000>热喷涂是指一系列过程，在这些过程中，细微而分散的金属或非金属的涂层材料，以一种熔化或半熔化状态，沉积到一种经过制备的基体表面，形成某种喷涂沉积层。涂层材料可以是粉状、带状、丝状或棒状。热喷涂枪由燃料气、电弧或等离子弧提供必需的热量，将热喷涂材料加热到塑态或熔融态，再经受压缩空气的加速，使受约束的颗粒束流冲击到基体表面上。冲击到表面的颗粒，因受冲压而变形，形成叠层薄片，粘附在经过制备的基体表面，随之冷却并不断堆积，最终形成一种层状的涂层（见图1、图2）。该涂层因涂层材料的不同可实现耐高温腐蚀、抗磨损、隔热、抗电磁波等功能。自1908年瑞士工程师Max Ulrich Schoop发明热喷涂以来，该工艺得到不断完善和发展。今天，热喷涂作为一项高科技工艺已广泛应用于航天、汽车、能源、钢铁、冶金、造纸、机械维修、市政建设等诸多领域。在中国，热喷涂还是连续四个"五年计划"推广的科学项目。</FONT></FONT></P>

<P><FONT size=4><FONT face="Arial, Helvetica, sans-serif" color=#ffffff>cccc</FONT><FONT face="Arial, Helvetica, sans-serif" color=#000000>在工程、机械的表面领域，热喷涂技术是最有效、最省钱和最直接的增强表面功能和工艺参数的方法。能够通过热喷涂手段改进和提高的表面种类几乎是无限的。通过喷金属、陶瓷、合金、重熔等等工艺手段，工程表面的功能概念得以延伸。</FONT></FONT></P>

Re: 什么是热喷涂？

用过热喷涂效果还不错，就是费用高了一些。对这项技术不是很了解。

Re: 什么是热喷涂？

某单位的柱塞原先用镀硬铬,使用效果不理想,后改热喷涂合金粉,车间技术人员自查资料,用车床旋转,氧气加热,因没掌握技能,出现了流挂,隔层现象。
后请合金粉厂商来指导,成功了.喷涂前柱塞先喷砂处理除油除锈,他们从旋转速度,喷砂量,加热温度作了改进,具体工艺参数不清楚.再车、磨。

Re: 什么是热喷涂？

漂泊打工者,我现在也在学习热喷涂设备。我们公司在做德国喷涂设备的代理，你们单位打算上哪的喷涂设备？有空找你交流！
