Embodiment Construction

[0026] The material is made by the following method:

[0027] Add a certain amount of boron-iron alloy powder with a certain amount of nickel powder to make it reach the required composition ratio, and then add an appropriate amount of gasoline or alcohol as a ball milling medium for ball milling. The time is 15-20 hours. The powder obtained after ball milling The compressed powder is obtained by drying and blending. Put an appropriate amount of the compacted powder into the piston ring die for compression molding to obtain a compact, then place the compact in a sintering furnace and sinter at a temperature of 1100 to 1250°C for 20 to 40 minutes to obtain a piston Ring blank,

[0028] The finished piston ring can be made from the blank after simple machining.

[0029] A specific example is given below:

[0030] Take 1000 grams of ferro-boron alloy powder with a particle size of 60 mesh and a boron content of 12%, and add 250 grams of 100 mesh nickel powder. At this time, the conte...

Abstract

The wear-resistant metal material for making piston ring consists of B 2-13 wt% and Ni 3-27 wt% except Fe, and is produced through powder metallurgical process. The material is used in producing piston ring with high use performance for piston engine. The piston ring producing process is simple and needs no chromium plating, molybdenum spraying or other surface treatment.

Description

Technical field [0001] The invention relates to a wear-resistant metal material. [0002] The use of the wear-resistant metal material to manufacture the key part of the piston engine, the piston ring, can not only improve the use performance of the ring, but also greatly simplify its manufacturing process. Background technique [0003] Piston ring-----A type part of piston engine, it is one of the key parts. [0004] It is one of the earliest branches in the internal combustion engine industry. Among the numerous internal combustion engine parts, the piston ring is the most demanding part. Its performance has a decisive influence on the overall performance of the engine and the emission of automobile exhaust. [0005] The piston engine was born for more than a hundred years, and the piston ring has been produced for more than a hundred years. However, due to the particularity of the piston ring parts, its manufacturing materials and manufacturing processes have not changed much ...
