Organic rare-earth energizer for chemical heat treatment

Abstract

The invention relates to an organic rare-earth energizer for chemical heat treatment and provides a surface chemical heat treatment energizer for a metal product. The energizer has the advantages of high activity, low cracking temperature, simple prescription, no pipeline blockage, and the like. The energizer not only can improve the catalysis speed and reduce the catalysis temperature, but also can obviously improve the brittleness, the wearing resistance and the contact fatigue and the flexural fatigue life of a catalyzing layer, has safety, reliability and stable product quality, greatly reduces the energy consumption in the heat treatment process, increases the heat treatment speed by 25 percent to 50 percent and reduces the energy consumption by 30 percent to 55 percent by the cooperation of rare-earth metallocene and ferrocene. By using a mixture of the rare-earth metallocene and the ferrocene as a main component of the energizerm, and the energizer has low the cracking temperature, can solve the problem of blocking a pipeline in the heat treatment process and can be used in the solid catalyzing and liquid catalyzing fields.

Description

technical field [0001] The invention relates to an organic rare earth penetration accelerator for chemical heat treatment technical background [0002] The surface chemical heat treatment of metal products is to change the surface phase structure of metal materials through thermal penetration of elements such as carbon and nitrogen, thereby improving the surface mechanical properties and corrosion resistance of materials. It has become a necessary process for some metal products, such as automobile chassis, bearings, Gears, piston pins, chains, tracks, tools and more. However, the energy consumption of surface heat treatment is high and the process lasts for a long time. Therefore, infiltration technology can be used to accelerate the chemical heat treatment process and reduce energy consumption. [0003] Rare earth is a very active element. Rare earth is used in the carburizing process. It is generally believed that rare earth has four functions: [0004] One is to optimi...

Problems solved by technology

In 2005, Harbin Yifeng Rare Earth Material Development Co., Ltd. applied for the patent "Organic Rare Earth Chemical Heat Treatment Infiltration Catalyst and Its Application" to solve the problem that rare earth chlorides are prone to clogging dropper failure during use. The organic rare earth infiltration catalyst was invented. The main composition of the agent: 8-12% rare earth elements, 5-8% tetrachlorethylene, 1-4% rare earth metallocene, 0-30% ammonium isobutyrate, the balance of isomeric acid and isomeric alcohol, which can be used to prepare carburizing and carbonitriding catalyst

According to reports, this osmotic agent can better solve the problem of blockage of pipelines caused by inorganic osmotic agents, but the components of this rare earth osmotic agent are relatively complicated

[0014] At present, inorganic osmotic agents have the problems of low activity and serious blockage of pipelines, while organic osmotic agents have solved the problem of pipeline blockage

However, the formula is complicated, the cracking temperature is high, the activity is also low, and the amount of addition is large, etc.
