How do I calculate deposition rate for a thermal spray process?

Deposition rate is feedstock feed rate times deposit efficiency, giving deposited mass per minute on the part. The Deposition Rate calculator uses your powder or wire feed and the process deposit efficiency, often 40 to 70 percent for plasma and higher for HVOF or arc, to return grams deposited per minute. Combined with Coating Area and Coating Thickness Buildup, it sets Spray Time Per Part and drives booth scheduling.

How much powder does a coating job actually consume?

Consumed powder is the deposited mass divided by deposit efficiency, so overspray inflates feedstock well beyond the coating's own weight. The Powder Consumption calculator takes coating area, thickness, coating density, and deposit efficiency to return kilograms of powder per lot, and Overspray Loss quantifies the wasted fraction. Because powder is often the largest variable cost, a ten point efficiency change can noticeably move Coated Part Cost.

How do I estimate spray time per part?

Spray time is the deposited volume needed divided by deposition rate, plus indexing between passes. The Spray Time Per Part calculator combines Coating Thickness Buildup and Deposition Rate to return torch-on minutes, and Robot Path Time adds traverse and index moves. Multiplying by lot size and dividing into available booth hours through Booth Utilization tells you whether the booth or a prep station is your throughput bottleneck.

How is masking and prep labor factored into coating cost?

Prep and masking are labor hours that ride alongside torch time and often dominate on complex geometries. The Masking Labor Cost calculator prices tape, shielding, and fixturing time per part, while Grit Blast Prep Time sizes surface preparation. These add to Spray Time Per Part and Finish Grind Allowance so the Coated Part Cost reflects the full route, not just the deposition step that spec sheets emphasize.

How much finish grind stock should I leave on a sprayed coating?

As-sprayed coatings are rough and oversized, so you spray above final dimension and grind back. The Finish Grind Allowance calculator sets the extra thickness to deposit for a target finished size and surface finish, which feeds back into Coating Thickness Buildup and Powder Consumption since you are paying to deposit material you will grind away. Balancing allowance against grind time keeps both feedstock and finishing labor in check.

How do I build a quote price for a coated part?

Start with feedstock from Powder Consumption or Wire Consumption and Bond Coat Usage at real deposit efficiency, add Gas Consumption and Torch Wear Cost, then Spray Time Per Part, Grit Blast Prep Time, Masking Labor Cost, Robot Path Time, and Finish Grind Allowance for labor and booth time. Coated Part Cost sums these with Inspection Cost and expected Rework Cost, and Quote Price applies your margin while showing how deposit efficiency and lot size shift the number.

Thermal Spray, Hardfacing & Wear Coatings calculators

This category covers the numbers behind thermal spray, hardfacing, and wear coating jobs, from deposition rate and feedstock consumption through spray time, overspray loss, and finished coated part cost. It is built for coating engineers, booth operators, and estimators who need to price and schedule plasma, HVOF, arc, and flame spray work with real deposit efficiency in mind.

Best calculators in this category

Deposition Efficiency: Calculate deposition rate for thermal spray, hardfacing & wear coatings planning, quoting, troubleshooting, capacity review, or process improvement.
Powder Consumption: Powder consumption tells a thermal spray shop how much feedstock it must actually load into the hopper to build a coating on a given surface area, after accounting for the powder that never lands on the part.
Wire Consumption: Wire consumption tells a thermal spray shop how much solid or cored wire it must feed to build a coating over a given area on twin-wire arc or combustion wire (flamespray) equipment.
Spray Time Per Part: Spray time per part converts a coating workload into a realistic cycle time, so a thermal spray cell knows how long the gun-on and handling time will actually run.
Coating Reject Rate: This calculator measures the reject rate on a thermal spray batch, the share of coated parts that fail inspection for defects like poor adhesion, spallation, out-of-spec thickness, or excessive overspray on masked features.
Masking Labor Cost: Masking labor is one of the most under-estimated cost drivers in thermal spray and hardfacing work, where every bore, thread, keyway and sealing face has to be shielded from overspray before the gun ever fires.
Bond Coat Usage: Before nearly any thermal spray topcoat goes down, a bond coat such as NiAl, NiCrAl or a MCrAlY tie layer is sprayed to key the ceramic or carbide to the substrate.
Spray Booth Throughput: On a busy thermal spray line, knowing how many parts a booth actually clears per hour drives scheduling, capacity planning and delivery promises.
Booth Utilization: A thermal spray booth is a capital-heavy asset with hoods, dust collection, robots and acoustic enclosure, so idle booth time is expensive.
Rework Cost: Rework Cost tells a thermal spray shop what it actually spends re-blasting, re-masking and re-spraying coatings that failed inspection, bond-test rejects, out-of-tolerance thickness, or spalled hardfacing.
Grit Blast Prep Time: Grit Blast Prep Time estimates how many booth hours it takes to bring parts to the anchor-tooth surface profile that thermal spray and hardfacing coatings need to bond.
Robot Path Time: Robot Path Time estimates how long the spray robot spends actually traversing the programmed path to lay down a thermal spray or hardfacing coating.
