Introduction An effective CSLP is vital to a construction project as it can improve efficient operations such as minimize travel time, decrease materials handling time by avoiding the obstruction of materials as well as plant movements and ensure safety of a site working environment.
Thus the #1 material lay-down area could service Building 3 and Building 4 and the #2 material lay-down area could service Building 1 and Building 2 effectively.

The microstructure of plasma-sprayed NTB coatings is very similar to that of initial NTB bulk materials.
The wear track on the NTB10 pin has typical signs of adhesive interaction such as tearing and adhering of materials (Fig.3a).

Currently, the methods of drilling hard and brittle materials include grain machining, which is a mechanical method, electronic beam machining and laser machining.
When these difficult machining materials such as Stainless Steel, aluminum alloy, super alloy and titanium alloy are drilled, the scraps are not easily broken off in the drilling process.
So, it is especially important for drilling chip to be disposed when these difficult-to machine materials are drilled.

Effect of pin material on COF & wear.Testing was carried out on LST discs made of HSS and pin material of type MS, EN31 and SS under dry and wet condition.
The least efficient amongst the group of pin materials was MS, which showed Highest COF and wear parameter readings for both Wet and Dry conditions.
· The wear and friction trends revealed innovative technique and novel knowledge in terms of structure and surface quality for science of tribology.
