Gas turbine bearing  laser cladding repair

Product description：

In a steam turbine, the bearing bush is one of the important components of the bearing. During operation, besides, to wear with the journal, it also bears the load transmitted to it by the journal. Therefore, the bushing material should have a small friction coefficient and a good anti-friction effect. And has sufficiently high compressive strength and toughness.

Tin-based babbitt alloy meets the above performance requirements, and the phase composition with high hardness is distributed on the soft phase matrix, which is a very suitable bushing material.

Compared with other tin-based babbitt alloys, SnSb11Cu6 has the smallest linear expansion coefficient, high thermal conductivity, high corrosion resistance, and fatigue resistance, and is suitable for high-load, medium-hardness around HB300. It is a bearing bush widely used to support the rotor in steam turbines.

During the operation of a steam turbine, oil cut-out and tile burning sometimes occur. Under the traditional method, tile replacement or re-pouring is used to solve the problem. The use of laser cladding technology to repair the bearing can quickly repair the bearing locally, saving time and cost.
