Title: Production method of valve spring
Inventor: AMANO NORIMITSU
IPC: F01L3/10
Filed: 2003-11-20
Abstract: <P>PROBLEM TO BE SOLVED: To provide a method for setting the optimum nitrogen potential in nitriding treatment of a valve spring.  <P>SOLUTION: After carrying out nitriding treatment in a nitrogen gas atmosphere within a first concentration range, another nitriding treatment is carried out in a nitrogen gas atmosphere within a second concentration range which is lower than the first. A high nitrogen gas concentration increases the nitrogen concentration at the surface of the valve spring and forms an Fe<SB>2</SB>-<SB>3</SB>N layer. After forming the Fe<SB>2</SB>-<SB>3</SB>N layer on the surface, the nitrogen gas concentration in the atmosphere is lowered, which inhibits the formation of a new Fe<SB>2</SB>-<SB>3</SB>N layer on the surface. Meanwhile, the existing Fe<SB>2</SB>-<SB>3</SB>N layer is dissolved, and the resulting nitrogen N diffuses into the interior and dissolves in ferrite to perform reinforcement intended inherently by nitriding. The 2-stage shifting (from high to low concentration) of the concentration enables deeper nitriding treatment within a shorter time.  <P>COPYRIGHT: (C)2004,JPO&NCIPI
