Coated alloy wear plate is designed to settle the wear issue of the wear plate laterally fixed on the interior lifting guide channel of ballast cleaning machine by plasma cladding alayer of wear-resistant alloy on the wear surface of the plate to tackle the moderate wear strength of the plate so as to increase service life of the wear plate. The plates feature the following characteristics:

1. High welding strength to protect the layer from scaling off.

2. Adopting automatic welding technique to ensure a smooth and flat surface that reduces friction.

3. More than 10 times of service life improvement.
