The green laser pointer company will perform the system reform

Of metal phase transformation hardening (or known as surface hardening, surface amorphization, surface remelting pure fire), surface alloying, surface modification, resulting in quenching with its surface reach the surface composition, organization performance of the change. After laser treatment, cast iron surface hardness can reach HRC60 degrees in carbon and high carbon steel, the surface hardness up to HRC70 degree, thereby improving the abrasion resistance, fatigue resistance, corrosion resistance, antioxidant and other properties, to extend the their useful life. laser heat treatment technology and other heat treatment such as high-frequency quenching, carburizing, nitriding, etc. traditional process compared. The quality of    green laser pointer   cannot be ensured with the technical problem unsolved.
Has the following characteristics: 1. Without the use of additional material, only to change the deal with the organizational structure of the surface treatment of the modified layer has sufficient thickness may need to adjust the depth of generally up to 0.1-0.8mm 2. Processing layer and bonding strength between the laser surface treatment of the modified layer and the substrate material is dense metallurgical bond, and the processing surface is dense metallurgical organizations, has a high hardness and wear resistance. handle deformation very small parts is a very short duration of action due to the high laser power density (10-2-10 seconds), so parts of the thermal deformation and the overall changes are small. Therefore suitable for high-precision parts processing, as the last treatment processes of materials and components. The    green laser pointer       is a kind of laser product.
Processing flexibility, wide range of applications. Flexible light guide system free laser-oriented processing section, which can easily handle the deep hole inside the hole, blind holes and grooves can be selective partial treatment. According to atomic physics theory and quantum theory shows that the composition of the material particles in a series of discrete energy levels, the lowest energy state for the ground state, other than the ground state energy state is called excited states. In the case of thermal equilibrium, any two of the high and low energy levels, particle number distribution follows the Boltzmann statistical law: where nl and n2 to level the E1, E2, the number of particles. The E1 <E2,所以n1> n2 is in thermal equilibrium, the level of any two energy levels, the energy level number of particles constant number of particles less than the low energy level, as shown in Figure 1-l (a) as shown. But under the incentive of external energy (heat, light, chemical energy, etc.). The price will be cut a little bit for the large purchase quantity of   usa green laser pointer  .
Can make the particles absorb energy on the low energy level transitions to high energy level, making n2 is> n1, the material to achieve a population inversion between the energy level and low energy levels, as shown in Figure l-1 (b) below. Substances in the state of population inversion is called the active substances or substances. Spontaneous emission, stimulated absorption and stimulated emission. The laser is through the interaction of light with matter, especially the role in the process of stimulated emission of radiation. The concept of stimulated emission is that Einstein first proposed in 1917. From the point of view of quantum theory, Einstein proposed the following three processes: spontaneous radiative transition of particles included in the process of interaction of radiation with matter, the stimulated emission transition and stimulated absorption transition. The green laser pointer company will perform the system reform.
Subject to shock transition and the spontaneous transition are two fundamentally different physical processes. Spontaneous radiative transition probability A21 only with the nature of the substance itself; stimulated emission transition probability W21 and stimulated absorption transition probability W12 not only related to the nature of the substance, with the radiation field of radioactive materials, the energy levels of high and low level degenerate when the degrees equal, W21 = W12. In addition, the spontaneous emission light non-coherent light, the wavelength, phase, direction of propagation and polarization direction are random, erratic; while amplification by stimulated emission of identical photons can be induced by the incident photon can be achieved with state photon number photon Jane, which can be obtained very high degree of coherent light. The company plans to revise the basic policy of   green laser pointer      workshop.
