Influence of Compound Modification Treatment on Inclusion Formation Characteristics of Low Alloy Wear Resistant Alloy

Wear resistant alloys (WRAs) are widely used in industries due to their excellent wear resistance and corrosion resistance properties. Low alloy wear resistant alloys 800 (WRA800) is an example of one such alloy, widely used in the automotive and aerospace industries due to its superior mechanical properties. In order to enhance the properties of WRA800 and to further improve its performance, compounded modification treatment has been employed. The compounded modification treatment is a process where two or more elements, usually in solid form, are added together in order to form a single, more complex alloy.
    
The purpose of this study was to evaluate the effect of compounded modification treatment on the inclusion formation characteristics of WRA800, which are responsible for its corrosion resistance and wear resistance properties. Tests were conducted using a Bridgman furnace where specimens of WRA800 were heated to different temperatures and pressure changes were applied. The results of the tests revealed that with the increase of the heating temperature, the level of inclusions in WRA800 decreased. Specifically, the highest inclusion formation was observed at 1000 degrees Celsius, followed by 900 and 800 degrees Celsius, respectively. The lowered levels of inclusions due to the compounded modification treatment can help improve the performance of WRA800, as it would reduce the risk of particle embedment and erosion.

The compounded modification treatment also affects the microstructure of WRA800. The modified WRA800 alloy exhibits a finer microstructure, compared to its standard form. This finer microstructure improves the grain size and further enhances the wear resistance and corrosion resistance of the alloy. The results of this study may be beneficial to the automotive and aerospace industries, as they can be used to optimise their manufacturing techniques and processes to enhance materials performance.
    
In conclusion, this study demonstrates that the compounded modification treatment has a clear role in affecting the inclusion formation of WRA800. The findings of the study can be used to modify the thermal treatment of WRA800 and further improve its properties. This study will help manufacturers to more optimise their processes and enhance their products' performance.
