本文介绍利用氢化钛粉在普通钢铁基体上形成烧结涂层的方法。该法工艺简单、设备投资少。工艺要点是在氢化钛粉中配一定量粘结剂,加水调成糊状,均匀涂抹在钢铁基体表面,烘干后放在真空烧结炉内(1×10~(-4)毫米汞柱以上的真空度),温度在1100～1150℃,烧结0.5～1小时,形成涂层厚度达100微米以上。孔隙度在0.4%以下、牢固不易脱落的钛涂层。它有一定的耐蚀性,在某些稀酸、碱、盐中耐蚀性接近纯钛。涂层经氮化处理后耐蚀性超过纯钛。
This article describes the use of titanium hydride powder in the ordinary steel substrate sintered coating method. The process is simple, less equipment investment. The main points of the process are adding a certain amount of binder in the titanium hydride powder, adding water to form a paste, applying it evenly on the surface of the steel substrate, drying it in a vacuum sintering furnace (above 1 × 10 -4 mmHg) The degree of vacuum), the temperature at 1100 ~ 1150 ℃, sintering 0.5 to 1 hour to form a coating thickness of 100 microns or more. Porosity below 0.4%, solid hard to fall off the titanium coating. It has a certain corrosion resistance, corrosion resistance in some dilute acid, alkali, salt close to pure titanium. After nitriding coating corrosion resistance than pure titanium.
