Beschreibung
Zusammenfassung:	The invention belongs to the technical field of materials, and discloses a valve and a strengthening method and application thereof. The strengthening method of the valve comprises the following steps that the surface of the sealing face of the valve is pretreated; the alloy attaching piece is compounded to the surface of the valve sealing face, and a composite layer is obtained; the alloy laminating sheet comprises the following components in parts by weight: 8-16 parts of chromium, 6-10 parts of nickel, 18-22 parts of cobalt, 2-5 parts of iron and 47-56 parts of tungsten. According to the valve strengthening method provided by the invention, the alloy attaching piece is compounded on the sealing surface of the valve, so that the alloy attaching piece is firmly combined with the sealing surface of the valve, the sealing surface of the valve has corrosion resistance and wear resistance, the sealing surface of the damaged valve is recycled, and the service life of the valve is prolonged. The valve strengthenin
