Understanding the Enhanced Protective Mechanism of CoCrNiAlY–YSZ–LaMgAl11O19 Double-Ceramic Coating with Aluminum Plating

Coatings (2021)

Junfei Xu Zhiguo Wang Shuai Hu Yongjun Feng Suying Hu

To understand the enhanced protection mechanism of CoCrNiAlY–YSZ–LaMgAl11O19 double-layer ceramic coating with aluminum plating, a finite element simulation method was used to simulate the distribution of thermal stress in the coating in all directions. The results show that in the air exposure of the un-aluminized coating, high temperature causes a large radial thermal stress on the surface of the LaMgAl11O19 (LMA) layer, and it increases with the increase in temperature, which is the main reason for the initiation of axial cracks. After arc aluminum plating, the aluminum plating layer effectively inhibited the volume shrinkage of the coating through good adhesion to the coating and internal diffusion; the thermal stress of the coating was considerably reduced; and the CoCrNiAlY–YSZ–LMA coating had an effective enhancement and protection effect. However, there was still a certain amount of shear thermal stress inside the LMA layer, the top of the crack, and the bottom of the crack. This thermal stress caused the initiation of radial microcracks in the LMA layer, which also becomes a risk point for the failure of the aluminum coating.

Development of the Two-Dimensional General Mechanical CAD System

Advanced materials research (2013)

Yongjun Feng

Although the function of Auto CAD is powerful, its professional pertinence is weak, and partuicularly it cannot satisfy the requirement for the efficient drawing and annotation of the common mechanical structure. The author of this paper has a discussion on the development principle and methods of a 2D General Mechanical CAD System (MACD). Faced up with all the requirements of the mechanical designing 2D drawing, and on the basis of the overall extracting the special features of the mechanical structure 2D primitives, the designing habits and the designing standards and specifications, all the function points of the system have been set up through the intersection and integration of the Auto CAD working mode and the functions of the system. A mechanical CAD system with a general drawing fucntion has been complished with a comprehensive use of the tools of the Auto CAD like function expansion, menu customization and programme development. Applied practice shows that this system has satisfied all the requirements for the mechanical desginers to make the drawings, annotations, enquiry for the standard data, the structure enquiry and quotations so that the designing efficiency has been greatly increased.

A study on the informatization programming of equipment manufacturing industries

Yongjun Feng

It is well-known that a scientific information programming is the key success factor for the equipment manufacturing industries. Because of the complex operation flow and heavy operation data, there exist many difficulties in the information system building all the time. In this paper, based on the detailed analysis of this kind of enterprise's information core factors, it proposes a new basic strategy and flow for the information programming, using critical success factor method, which can provide a programming method for the information system building of equipment manufacturing industries, furthermore it is a guidance for the other industries.

Frictional Study on 30CrNi2MoVA Steel Based on Experiments and Finite Element Simulation: Wear Prediction

Coatings (2024)

Ao Wei Yiyi Li Lianghai Feng Yongjun Feng Zhiwen Xie

30CrNi2MoVA steel demonstrates excellent performance, meeting the requirements of a crucial material for high-load structural parts. However, after experiencing high loads and thermal cycling, the material undergoes wear on its contact surfaces, resulting in a certain wear depth that determines its service life. Therefore, accurately predicting and evaluating the wear performance and wear depth of this material is of paramount importance. This study employs a combined approach of experimental and simulation methods. Initially, friction and wear tests were conducted to investigate the wear behavior of the 30CrNi2MoVA steel. The experimental results reveal a significant influence of thermal cycling temperature on the material’s wear resistance, with wear mechanisms primarily attributed to adhesive wear and abrasive wear. Subsequently, a ball-on-disc wear model was established. Based on experimental data, the modified Archard model was implemented as a user subroutine in finite element software (ABAQUS version 2020) to assess the material’s wear volume. The simulation results demonstrate a close agreement with the experimental wear depths. Furthermore, a fitting formula was developed to correlate the wear depth of the material with the number of wear cycles, enabling accurate wear depth prediction. This study provides theoretical support for enhancing the performance and extending the service life of 30CrNi2MoVA steel.
