A compressive stress layer is formed.
8 characteristics of MPI
MPI acts as a protective film that minimizes adhesion on aluminum die casting molds.
MPI creates micro-depressions on the metal surface, enhancing PVD coating bonds.
Reduces surface friction, enhancing the material's flow and release properties.
Effectively removes white layers and unstable layers from nitrided and carburized molds, extending their service life.
Effectively remove internal stress and increase compressive stress from 800mpa to 1400mpa
Facilitates uniform carbon diffusion, enhancing the density of carbon-based coatings and making them less prone to peeling.
Increases metal surface hardness by about 40% (10-20μ)
MPI causes micro-depressions that create reservoirs for lubricating oil, preventing film compression and damage, enhancing lubrication efficiency.

MPI is usually carried out under rapid heating and cooling conditions, which enables the target metal to achieve surface hardening, forging and heat treatment effects, thereby increasing internal compressive stress.
