Thermal spraying involves forming continuous layers of coatings of metal, ceramic or plastic by dissolving these materials using heat and then utilizing compressed air to particlize and blow the particles at high speed onto the surface of an object.

Thermal spraying can be used for countless applications and it is expected to become an innovative new surface treatment technique for the field of rust and corrosion prevention through the development of heat sources and materials as well as improvements in control technologies and spraying methods.

Advantages of Metal Spraying

■Extends the life of steel by electrochemically preventing corrosion
■Easily able to select the thermal spraying coating tailored to the specific corrosion prevention needs
■Metal spraying equipment is mobile making work possible in the factory or onsite
■No limits on the size of the components that can be sprayed
■Easily able to treat the surface of steel without heat warping
■Can select the best thermal spraying coating for the job
■No hydrogen embrittlement
■Ideally suited as a base coat for treated surfaces

Categories of Thermal Spraying

Thermal spraying is categorized as follows according the heat source used.

Thermal Spraying Workflow
Product arrival
Components or finished products fabricated in the customer's factory arrive at the Ishikari Factory.
Surface preparation process
The surface is prepared and cleaned using a blaster
((ISO8501-1Sa3.0)
Thermal spraying process
A wire flame sprayer is used to coat the surface with either zinc, aluminum or their alloy.
Sealing process
Pinholes and other imperfections left on the surface are filled and sealed. The sealing process uses a special agent or a mist coat when using paint.
