casting parts

The main causes of poor plasma nitriding of precision casting parts are heat treatment temperature, heat treatment time, nitrogen concentration,

1. Chemical composition of corrosion products on the surface of cast parts In order to prevent other foreign impurities from

Precision casting Vickers hardness test is a kind of indentation hardness test. The value of Vickers hardness has nothing to

The common characteristics of cast steel are high melting point, poor fluidity, large shrinkage, easy oxidation and inclusion. During casting,

A number of heat-treated samples with the size of 15 × 15 × 15mm were selected from the successful parts.

The results show that the strength of 7075 rheo squeeze casting parts can be greatly increased by aging treatment. The

The Brinell hardness values of 7075 rheo squeeze casting samples after solution treatment at different time were counted in the

It can be seen from the metallographic structure figure 1 after solution treatment at different temperatures for 2 h that

In order to improve the quality of wheel shaped squeeze casting parts, the process parameters of different extrusion filling speeds

Drawing is to adjust the taper of the mold or casting surface so that the mold and product can be

Because hot joints will occur in large and thick parts during the cooling process of castings, and casting defects such

After filling, in order to analyze casting problems such as subsequent solidification defects, the solidification temperature field is further analyzed.
