Question 2
1 Soldering Materials selection and specific reasons
Copper and Silver based alloys
Silver-based alloys have always been
preferred for the process of soldering in

various applications. This is because its
figurative value is almost competing
with that of gold. Silver alloys are very
much compatible with most of the metal
components. Its application is limited to
these areas where the temperature is not
expected to go higher than 900 degrees.
They provide proper strength and
compatibility.
2 Friction Welding In most of the cases, the preferred
material for such joining is alloys of
aluminum. These alloys are used more
due to their workability which is
relatively superior and less affordable in
terms of cost. In cases where proper
friction welding with superior
weldability and good strength are
required, stainless steel and aluminum
material may be used.

Question 3
Surface Processes
Component of engineering Surface process
In this particular component, the
surface finishing process used is
called electroless plating. The
reduction agent that replaces
electricity has been used in place to
induce fabric or polymer material.
The type of surface finish that has
been illustrated here is called
painting by the use of electricity. It
is commonly called electropainting.
It has basically been used to achieve
surface decoration and anti-
corrosion properties (Berto and
Lazzarin 2014).
Question 4
Advantages of using surface finishing process on the material components
I. Some of the surface finishing processes enhance the aesthetic value of the component
like painting for decoration.
