Heat can be damaging to PVD coating equipment, so it is important to learn how to prevent PVD equipment from overheating. PVD stands for “physical vapor deposition” and is a method used by physical vapor deposition coating equipment like PVD arc ion plating equipment, PVD sputter coater equipment, PVD vacuum evaporator equipment, PVD reactive sputtering equipment, PVD ion beam mixing equipment and more.
Possible Ways To Prevent Coating Equipment From Overheating
The first way to keep PVD coating equipment from overheating involves limiting the amount of time that the machine runs without breaks. Although machines may still overheat if left running too long without breaks or maintenance periods, taking regular breaks prevents overheating at high PVD coating speeds. PVD coating equipment can take breaks automatically if possible, but it is also important for PVD coatings workers to know the amount of time that PVD coaters should remain running without maintenance or PVD break periods.
The second way to prevent PVD coating equipment from overheating involves using external cooling coils on PVD machines. An external cooling coil PVD cooler works by transferring excess heat away from the PVD machine and depositing it at a location outside of the PVD chamber itself. This prevents PVD equipment like sputtering coaters, evaporators, arc ion plating systems and others from reaching dangerously high temperatures that lead to damage.
Every type of PVD coating uses either an internal or external PVD PDC cooler system to transfer heat away from PVD coating equipment. PVD PDC coolers help keep PVD coaters running at their highest speeds with the least amount of damage. Contact PVD PDC cooler manufacturers for more information about how PVD PDC coolers can prevent overheating in PVD coating equipment.
The third way to prevent PVD coating equipment from overheating involves using liquid nitrogen or other cryogens to lower the temperature inside of a vacuum chamber that houses the machine’s heating element. Cryogen cooling is used less often with newer models like fluidized bed arc ion plating systems, sputtering coaters and evaporators because it tends to slow down production rates when compared to external cooling coils or regular maintenance breaks.
Liquid nitrogen PVD cooling can also lower the effectiveness of PVD coatings like PVD titanium nitride or PVD chromium, resulting in poor quality PVD metal coating results. It is important to know the disadvantages of liquid nitrogen PVD cooling before incorporating it into PVD equipment, including its tendency to work less effectively by lowering production rates and reducing PVD coating quality.
The fourth way to prevent PVD coating equipment from overheating involves using water-cooled PDC coolers for dangerous vacuum chambers that house ionized hydrogen-based heating elements. Although these types of heating elements are dangerous if they overheat, water cooled PDC cooler systems can safely dissipate heat while leaving other parts open for PVD PDC cooling. PVD PDC coolers need to be placed in vacuum chambers that house PVD coating equipment like PVD arc ion plating systems, PVD sputtering coaters and more.
The final way to prevent PVD coating equipment from overheating involves having the parts of the PVD machine made out of materials with high thermal conductivity ratings. Materials with high thermal conductivity resist heating up while dissipating heat away from the PVD machine so it stays safe for use by PVD coating workers.
Whether PVD coating equipment is left running for too long without maintenance, using PVD PDC coolers or water-cooled PVD cooling systems, it’s important to keep PVD machines from overheating. PVD coatings like PVD titanium nitride and PVD chromium may be reduced in quality when PVD coating equipment overheats.
