Surface treatments are often used to improve the strength of surface and subsurface layers of hot-working dies in order to mitigate against the damages due to both thermal and mechanical stress.
Once the surface of the steel becomes amorphous its thermal conductivity can reduce by a factor of ten [27, 28].
The work presented here is focused on the development of a technique to achieve surface glazing and to assess the effect of laser processing parameters on the type of surface structures developed and associated mechanical properties.
A typical surface microstructure affected depth of 150 µm was noted however this varied depending of the processing conditions.
Samples 3, 9 and 17 had an affected region of approximately 150 µm deep, whereas sample 10 showed an affected region 60 µm deep.

Based on several real projects with WSHP systems in Chongqing, three of them were selected for field testing to study the operation performance and key factors impact the operation energy efficiency of WSHP.
To analyze factors influencing system energy efficiency, the three typical systems were selected as Table1.
Additionally, the selection of water treatment equipment not only determines the quality of water that enters the heat exchanger but also affects the pumping resistance[6].
It shows that water temperature and operation temperature difference directly affect system energy efficiency.

However, the coarse needle-like primary iron-rich phase in this type of alloy is very easy to split the matrix, which seriously reduces the mechanical properties and plastic processing properties of the alloy, limiting the application of the alloy [1-2].

Therefore, controlling the amount of residual austenite and its chemical stability (i.e. carbon concentration) greatly affects the property of the steel.
On the other hand, for the carbon concentration analysis, the location of diffraction peak center, i.e. the lattice spacing, is the most important factor while the variation of the peak height is not.
The final cooling step forms a few percent of martensite, but this is too small to affect the overall texture of the BCC phase (Fig. 6h).

However, the low-light conversion efficiency(10%~20%) causes most of the energy transform into redundant heat which ultimately increases the junction temperature, which on the one hand affects the LED optics output such as peak wavelength, on the other hand, which will significantly reduces the operating lifetime and reliability [2, 3].
The design of the structure of the heat sink is very critical factor to affect both the heat dissipation performance and cost of the LED lighting system.
These material properties are listed in tab.1.
In order to improve the heat transfer property of the LED lighting system, the sapphire substrate is replaced by the Si substrate and the copper substrate respectively.

However, tungsten components are traditionally manufactured by means of powder metallurgy or sintering methods [4], because of the intrinsic properties of high melting temperature (3422oC) and a high ductile-to-brittle transition temperature (DBTT) of about 400oC.
The high oxygen content may be another crack-effecting factor.
