Abstract:

Aluminium bronze alloys (Cu-Al-Fe) with Al > 14 wt. % are known to have high wear resistance and low friction coefficient against ferrous metals thus making it an ideal material for forming dies application. However, the use of these alloys has been restricted by the high cooling rate required to prevent embrittlement of the alloy during production. The plasma transferred arc technique (PTA) is an attractive production technique that offers the required high cooling rate, however the resulting microstructure is strongly dependent on the composition change induced during deposition. Therefore t

Abstract:

Modern railway transportation has imposed severe work conditions on the track. Wear of rails has become an important and costly phenomenon. Recent developments in the manufacture of rail steels have refined the interlamellar spacing to produce harder and more wear resistant pearlitic steels. Despite better nominal properties shown by bainitic and martensitic steels, pearlitic steels have shown lower wear rates. The aim of this study is to explain the mechanisms for the wear performance by observing how the lamellar pearlitic microstructure adapts to the wear loading. Four pearlitic rail steels

Abstract:

Polymeric coatings find applications in downhole water injector tubulars, protecting the inner surfaces from corrosion. Although these predominately epoxy-based coatings resist the harsh temperatures and pressures associated with a working injector, they are currently failing when exposed to mechanical damage. The mechanical damage takes the form of impact and wireline wear inflicted by the downhole 'tools' required in the maintenance of the injectors. In this work, experimental techniques have been developed for the successful direct observation of the impact and wireline wear damage mechanis

High hardness, fracture toughness, modulus of rupture and fine grain size are material properties that are desired for components employed in aggressive wear environments.

Tin alloy coatings have traditionally been used as corrosion resistant bamens due to their inert nature and comprehensive coverage, and have seldom been considered in physically demanding applications, such as wear resistant coatings owing to misconceptions associated with the soft nature of tin metal.

Unfortunately, its cyanide plating technology makes tin-copper environmentally unsustainable, whilst the

The necessity to improve the durability of the machinery used in the milling industry has lead to several types of research.

Thus, one type of approach to increase its durability is by reducing the material loss of the plates. Amongst all the parameters to reduce the wear ratio that includes inputs from geometry to load, just the hardness input of the material can be in constant development.

Zinc and its alloys are among the most widely utilised metallic coatings for the sacrificial protection of steel.

The Hypereutectic HCCI with large volume fractions of hard carbides is preferred to apply in wear applications. However, the coarser and larger primary M7C3 carbides will be precipitated during the solidification of the hypereutectic alloy and these will have a negative influence on the wear resistanc

碩士<br>臺北城市科技大學<br>機電整合研究所<br>105<br>This study is aimed to form oxide layers on surface of titanium metal by utilizing anodic treatment. In order to develop appreciated coloring and wear resistance, various voltages and electrolytes are used to obtain optimal conditions. 16 conditions of specimens are performed in the study, including 4 electrolytes, Na3PO4, NaOH, Sprite beverage® and Po petrol drink®, operating at different voltages. The voltages are 10V, 20V, 30V, 40V and 50V for the Na3PO4, NaOH; and are 30V, 40V and 50V for the Sprite beverage® and Po petrol drink®, respectively. The durat
