This study aims to use tea waste for the removal of Cu2+ ions.
The adsorbent, tea waste was characterized using a compound microscope and FTIR spectroscopy.
In 2012, Malaysia imported 215,041 t of refined copper and copper alloys and 13,523 t of copper scrap and exported 1,410 t of refined copper and copper alloys and 17,498 t of copper scrap.
The purpose of rinsing was to remove soluble and coloured compounds in tea waste [12].

Introduction Due to the high strength/weight ratio, good electromagnetic shielding and recycling ability, magensium and its alloys are widely used in many industries such as aerospace, automobile and communication fields[1].
However, magnesium alloys exhibit a poor corrosion resistance owing to the high chemical activity of the magensium.
The aim is to study the effects of duty cycle on the thickness, roughness, phase, morphology and corrosion resistance of coatings.

Introduction Titanium alloys and other metallic materials [1-3] are commonly used as biomedical devices due to their biocompatibility, mechanical properties and high corrosion resistance.
The aim of this work was the application of a bio-inspired intermediate layer, based on polydopamine, by dip coating on magnesium alloy AZ31 sheets, to regulate its corrosion rate.

XRD (X-Ray Diffraction) Tests were conducted to investigate compounds which form on the composite Al A356 / Al2O using SHIMADZU XRD, XRD-7000 machine.
Mg2Si intermetallic compounds formed on α-Al phase morphology Chinese script, as shown in Fig. 5.
(a) Si originate from Al alloy A356, will interact with Mg formed Mg2Si intermetallic compounds. 100µm 100µm 20µm (c) (b) (a) 100µm 100µm 100µm (d) (e) (f) Figure 4.
XRD Fig.9 was found compounds such as AlSi9, Al1,4Si0,3O2,7, Al2O3, Mg2Si, and MgAl2O4.
As described previously, Mg2Si intermetallic compounds emerged as a result of contact between Si content in Al A356 alloy with Mg added as a wetting agent.

The influences of alloy elements such as P, Cu, Cr, and C on the corrosion properties of steel were imitated and studied according to the model, aiming at offering references for corrosion behavior prediction of bainite weathering steel applied in this environment.
The improved corrosion resistance ability may be due to the formation of protective rust provoked by element P and the compact rust layers produced by Cu compounds, which aggregate around and fill the cracks and holes in rust layers [11-13].

The basis for most of these materials is rare metals and their alloys.
Due to their good mechanical, electrical, electro-erosive, tribological and magnetic properties, tungsten and its alloys are frequently used materials in industry [1].
With the aim to obtain a pure tungsten powder, the latest world research is oriented toward the application of new reducing agents and the development of new or a modification of existing technological processes.
