“…However unstable zone shows rough and show deep dimples and micron sized crack paths and craters. Coated samples showed only unstable crack growth region due to the strong bonding between the alloy and coating [8]. The stable fracture surface zone is in an elliptical form, ranging from about 2.2 mm to 2.4 mm in width.…”

Fatigue crack formation is the most important factor affecting the damage in parts under subjected to the repeated stresses. In this context, intensive researches are continuing on the protective hard coatings in the aviation and automotive sectors in order to increase the fatigue life especially in aluminum alloy parts. Chromium oxide (Cr2O3) based coatings are widely used in many industrial applications due to high corrosion resistance, high hardness and high surface resistance. In this study, fatigue crack propagation on 7075-T651 alloy with chromium oxide coating by thermal spraying method was investigated. Test results show that the crack propagation is slowed down by the chromium oxide based coating and increase the surface resistance of the aluminum alloy.

In this study, mixed mode I/III fatigue crack propagation is examined experimentally and numerically by using spherical porous cylindrical specimen. The crack propagation path, profiles of crack front, the differences of stress intensity factors (SIF) and equivalent SIF were computed by ANSYS, FCPAS and SOLIDWORKS softwares and compared with experimental data. Modeling, meshing and problem solving were performed using ANSYS, and the resulting SIF and equivalent SIF along the crack front were calculated using FCPAS. Two digital cameras were used to observing the crack growth path and fractured surfaces on specimen under mixed mode loading, and the obtained images were converted into 3D CAD data by using SOLIDWORKS software. It was found that good agreements were achieved between the results of the experiment and simulation considering both evolving the crack propagation paths and crack front.

“…Zinc-based aluminum rich alloy is a new non-ferrous metal material that has been widely used at home and abroad in recent decades [1,2]. Due to its low melting point, low density and excellent mechanical properties [3,4], it is widely used in coal, petroleum, aerospace and other fields [5,6]. With the development of social industry, people' requirements of zinc-based aluminum rich alloy's friction and wear performance are becoming higher and higher.…”

Aiming at the problems of poor bonding between the carbon fiber and the metal matrix and the friction and wear performance of the composite material during the preparation of carbon fiber reinforced zinc-based aluminum rich alloy composites, the carbon fiber surface metallization process was studied. Taking ZA27 as the research object, a new type of zinc-based aluminum rich alloy composite material was prepared by using surface metallized chopped carbon fibers with different contents as reinforcement materials. The microscopic morphology, element distribution and phase composition of the surface metallized carbon fiber and composite materials were characterized, and the hardness and friction and wear properties of the composite materials were tested. The results show that: the surface metallization of carbon fiber effectively reduces the diffusion of carbon elements into the matrix material during the sintering process, and improves the interface bonding between the carbon fiber and the matrix material; Compared with ZA27 alloy, the hardness of 6vt% carbon fiber is increased by 29.6%, and the average friction coefficient and wear rate are reduced by about 18.4% and 96%, respectively, indicating that the carbon fiber reinforced zinc-based aluminum rich alloy composite material optimizes the friction and wear performance of traditional materials.
