Surface Treatment Solutions

NICH Technologies works closely with our customers to ensure that we develop and implement the correct cleaning process required to meet the level of process control and system cleanliness for mission success. NICH Technologies continually invests resources into developing new processes and methods to meet the evolving demands of the industry. We always find new ways to control costs, while delivering components and products on time that meet strict quality requirements.

For companies looking to cut costs and improve efficiency, restructuring the precision cleaning function may offer the best opportunity to achieve these objectives. 


We offer a full range of cleaning services on critical process components proceed with decontamination, degreasing, selective chemistries, mechanical cleaning, and passivation.  After the cleaning treatment, we will conduct a critical feature micro level particle inspection to verify the specified cleanliness level.


Our in-house facilities allow us deliver excellent services in precision cleaning. For companies looking on cost improvement efficiency, restructuring the precision cleaning function may offer the best opportunity to achieve these objectives. 

Precision Cleaning Processes

Chemical Cleaning
Alkaline or Acid as an etching media use removing unwanted surface deposits such as organic residues or oxides and provide a smooth surface. Chemical cleaning always assisted by mechanical action, like ultrasonic or electrolytic cleaning.
Ultrasonic Cleaning
Uses cavitation bubbles induced by high frequency pressure (sound) waves to agitate a liquid. The agitation produces high forces on contaminants adhering to substrates like metals, plastics, glass, rubber, and ceramics. This action also penetrates blind holes, cracks, and recesses.
High pressure water blast cleaning 
Commonly known as hydro blasting, is a widespread abrasive water discharge operation. A technique for cleaning internal and external surfaces, which relies entirely on the sheer force of water from a pressurized source to achieve the desired cleaning effect on the intended surface. Water blast cleaning can effectively remove a wide variety of tough dirt in difficult-to-reach points or locations in a safe and efficient manner.
Passivation is the process of treating or coating a metal in order to reduce the chemical reactivity of its surface.The passivation process typically uses nitric or citric acid to remove free iron from the surface. This results in an inert, protective oxide layer that is less likely to chemically react with air and cause corrosion.
Abrasive Grit Blasting
Surface treatment operation of forcibly propelling a stream of abrasive material against a surface under high pressure. This process is used to safely remove oxidation, residue, discoloration and surface defects without altering surface component properties. Widely used in a variety of industries to clean or modify the surface properties of components.
Thermal Arc Spray
Thermal spray coating involves the use of a torch to heat a material, in powder or wire form, to a molten or near-molten state, and the use of a gas to propel the material to the target substrate, creating a completely new surface. The coating material may be a single element, alloy or compound with unique physical properties that are, in most cases, achievable only through the thermal spray process.

Thermal spray coatings are a highly cost-effective and straight-forward method for adding superior properties and performance qualities to a given engineering surface. 

Solvent cleaning (Degreasing)
The cleaning process usually use to remove surface contamination such as oil, grease, flux, grit, oxides, and metal debris or organic film from the surface.
