In the process the metal mechanical parts, the iron-based powder
metallurgy formulation process of application is very common, the iron-based
powder metallurgy formulation process is mainly the quenching process,
quenching purpose is to allow the iron-based powder after martensite
transformation to give specific organization, and then with a different
temperature tempering, powder metallurgy products, to improve the strength and
wear resistance.
To meet the different requirements of powder metallurgy products,
but also by the iron-based powder metallurgy technology for the formulation of
special properties of the products processed. Iron-based powder metallurgy
formulation process is characterized by the use of a vibration loading powder
method to change the density of distribution, making powder metallurgy
distribution, to prevent uneven added to discontent, reduce cracking and
failure occurs when induction hardening . Iron-based powder metallurgy
formulation process can reduce high-frequency induction heating quenching
frequency induction heating equipment, reduce the heating rate, reduce the
hardness difference is heated and unheated areas, so that produce hardness
buffers, reducing the risk of cracking.
In the iron-based powder metallurgy formulation process, and cracks
should use a dedicated jig to reduce high-frequency effects, internal workpiece
using cooling water to alleviate the amount of heat inside the powder
metallurgy products, reducing the stress and thermal stress uneven. With
iron-based powder metallurgy formulation process in production, effectively
prevent the occurrence of the crack phenomenon of powder metallurgy products.
Let the passing rate of the workpiece is greatly improved.
