Embodiment Construction

[0008] The present invention will be further explained below in combination with specific embodiments.

[0009] A piston ring for automobiles, comprising a piston metal ring and a ceramic film layer arranged on the metal ring, characterized in that: a NiCrAl layer is set between the metal ring and the ceramic film layer, and the NiCrAl layer penetrates into the Metal ring and ceramic film layer.

[0010] The piston ring for automobiles of the present invention is provided with a NiCrAl layer between the common metal ring and the ceramic film layer, and the NiCrAl layer penetrates into the metal ring and the ceramic film layer. After testing, the wear of the piston ring can be reduced and the piston ring can be improved. Excellent anti-sintering, effectively prolonging the life of the piston.

[0011] The piston ring for automobiles of the present invention has a simple structure. A NiCrAl layer is arranged between the common metal ring and the ceramic film layer, and the NiCr...

Abstract

The invention discloses a piston ring for an automobile, which comprises a piston metal ring and a ceramic film layer formed on the metal ring. The piston ring for the automobile is characterized in that: a NiCrAl layer is formed between the metal ring and the ceramic film layer and infiltrates into the metal ring and the ceramic film layer. According to the piston ring for the automobile, the structure is simple, the structure that the NiCrAl layer is formed between the common metal ring and the ceramic film layer and infiltrates into the metal ring and the ceramic film layer is provided, and therefore proved by tests, the abrasion to the piston ring can be reduced, the sintering resistance property of the piston ring is improved, the life of a piston is effectively prolonged, and the using requirements can be met.

Description

technical field [0001] The invention relates to an automobile, in particular to a piston ring for the automobile. Background technique [0002] At present, the piston rings commonly used in automobiles use a metal layer substrate as a structure, and a performance layer is plated on the metal layer substrate, such as a ceramic film layer, a nitride layer, and so on. This common structural form can meet the output requirements of the engine in a certain range, but with the rapid development of the automobile industry, the output torque of the engine is getting larger and larger, and the piston ring of this structural form gradually shows some abnormalities. The shortcomings of adaptation, such as short life, easy to pull cylinders, etc. Contents of the invention [0003] Purpose of the invention: In view of the deficiencies in the prior art, the purpose of the invention is to provide a piston ring for automobiles, so that it has the advantages of wear resistance, long life ...
