In for example the automotive and aerospace industries some mechanical parts are highly loaded with temperatures, corrosion and erosion. To protect them against these heavy influences, plasma spraying is the solution.
Plasma spraying is a flexible process and can be effective on ultra small to very big parts. Bronkhorst understands the market needs and can provide customized solutions to control the plasma spray process.
The plasma spraying process needs a high accuracy and stability of the plasma gas flow. Also the monitoring of the gas pressure is important for a good control of the plasma process. Bronkhorst can provide mass flow controllers and pressure controllers that are suitable for this. Bronkhorst also understands that a customized solution can be very functional for systems like plasma spraying.
In a special torch, a plasma jet will be created for
example by the plasma gas Argon. In the
plasma jet the temperature will reach almost
10.000 degrees Celsius. We can introduce a
powder (sometimes liquid) into the plasma jet.
Because of the high temperature the powder
will melt, and propelled towards a substrate.
There, the molten droplets flatten, rapidly
solidify and form a deposit.
The introduced powder can be made of various
metals, depending on layer thickness, function
of the deposit or physical properties. The range
of layer thickness at plasma spraying is 20
micrometers to several millimetres, depending
on the process and powder. There are a large
number of technological parameters that
influence the interaction of the particles
sprayed on the substrate. Parameters such as
torch offset, flow rate and energy input are
important. Because the plasma jet is created by
a controlled flow rate of the plasma gas, flow
controllers are crucial.
Monitoring the pressure is important to control
the system and detect an empty plasma gas
cylinder. Often the system will be expanded
with filters to be sure no other particulates will
be involved in the plasma spraying process.
